The Cornerplay: Xbox One's struggles are traceable to one bad decision

I don't think the RAM is the single point of failure for the console's success.

Quite frankly, both the X1 and the PS4 are significantly underpowered for a 2014 release. Hype can only push your product so far and it seems like a common sentiment that these "next gen" consoles are underwhelming at best.

The fact that nearly all developers are unable to hit the most basic 1080p @ 60fps is a pretty good indicator.

Where is this common sentiment???? BS, the sales speak for themselves..Ps4 is a sales monster still outpacing wii and ps2. Forums and hardcore techies is not sentiment.

A site called techspot says this"If MS had gone with 8 GB ram the hardware would be the same" WHAT??? Embarassing the ps4 has a considerable more powerfull GPU which is the bigger issue, faster ram is the least of x1's issues, faster ram doesn;t make much difference.

Also, when will people stop underestimating playstation?? WW it is dominant, even if Ms had a great launch, and hardware wise was on par ps4 would be winning, it is a stronger brand... Sony dominates Europe, Asia and emerging markets, MS as usual outside the US is weak....

Ps5 GPU, stronger brand are bigger issues not ram. Only reason 360 and ps3 were close was ms had a 1 year head start and sony launched at 600 bucks..
at least try reading the entire article. do you even know why the PS4 GPU is bigger? It's because of the 8GB of DDR3 RAM that the xbox one uses. More exactly the ESRAM that microsoft put in on the same APU die to increase the bandwidth since the DDR3 bandwidth would become a very big bottleneck. Sony doesn't need the ESRAM so they just used the extra space for a larger GPU.
So in theory, if MS had used GDDR5, the consoles would have similar power.

Mostly true. The Jaguar APU is capable of roughly 105 GFLOPs maximum throughput. The Xenon chip in the 360 was capable of about 115 GFLOPs, and the Cell maxed out at about 210 GFLOPs (though typical was only 160 GFLOPs due to coding difficulties).

Relative to PC's at the time of release, this is by FAR the weakest console generation ever. Remember the Xenos (~110 GFLOP) competed against the Pentium 4 (~10 GFLOP) and the Cell (~160 GFLOP typical) competed against the C2D (~35 GFLOP) when the consoles first hit. These CPUs, by contrast, are already weaker then their PC counterparts.

Point being: This is the first generation where CPU power DECLINED from the previous one. This occurred largely due to new TDP requirements in Europe, which basically forced sub-140W TDP consoles, meaning going toward APUs.

For me, the decision to choose the ps4 over xbox comes down to a statement by microsoft where they were considering the use of the kinect to count viewers watching the screen and the fact that you couldn't remove the kinect from operation. Of course those statements were reversed but it left a terrible taste in my mouth for the ways microsoft was considering using their hardware.

I read it did you???? The x1 still had kinect which drove the cost up 100 more...so even with GDDR5 there is no guarantee it would have had the better GPU as cost would go higher, in theory is right as this article is clearly talking out of there arse...MS tried to pull a DRM trojan horse and had features no one needs or wants, this is a much bigger issue then graphics power. That and Playstation keeps getting underestimnated by the ignorant american pres... News flash, head to head Playstation beats Xbox everytime Worldwide...It is just a bigger more popular brand. If not for the US xbox would have died years ago.

MS played there hand as to why they are really in the game market...and it backfired, no one wants that future...Sony stuck to gaming on a game console, go figure. MS wanted more power for app switching and multitasking, which are a waste of resources on what 90% of people buy a games console for, GAMING>

A year later and we are still getting 'lectures' from 'self' qualified 'experts'... Seriously?

Here:
http://www.eurogamer.net/articles/digitalfoundry-vs-the-xbox-one-architects

Now add in a years of SDK updates, expanded GPU access. Also go read up on how the thermal throttling of the AMD APU works and why the XB1 maintains more consistent FPS across games at even the same resolutions as the PS4.

Maybe 2015 will bring enough titles with the XB1 besting the PS4 to stop these nonsense articles and stop feeding the PS4 fans that were mislead by sites like this.


PS Search the web, and even just TECHSPOT itself. You can find a TON of articles on how the PS3 has superior hardware and will be faster than the XB360. And anyone that paid attention to history, this NEVER happened. The XB360 was not only as fast, but often offered higher quality graphics than the PS3 due to the new GPU that nobody understood beyond the 'raw' numbers that falsely seemed lacking.

The problem is 'tech-guessers' that think they understand the technology - which fails even when they are good, as this is often NEW technology that most people do not yet understand.

A Waste of resources? I'm guessing you dont own an Xbox One correct? I use those features every day, turning on my entire entertainment center, multitasking with party chat while playing a game, having the system record awesome moments by just telling it to. These are features that work and work very well WHILE you are gaming. Your friends jump on, its easy to just snap up the party chat and invite them in, all without leaving the game. I can zoom out to the dashboard and go watch a show on Netflix and then resume my game right where I left off. It works extremely well and the system was built and meant to do things this way and as a gamer, I really like what MS has done with the Xbox and their OS.

As far as sales go, both are selling way better than the previous generation, MS isnt doing bad at all really, Sony is just doing BETTER with the PS4. Shame though that even their amazing world wide sales cant bring the company to any profit, so how well is the PS4 actually doing when the entire company keeps posting major losses. MS is posting major gains almost every where in comparison and can put a lot more in the tank with their console.

The solution is very simple. The only they have to do is to bombard the ddr5 facilities. “…that’s how America does it, and it was worked out pretty well so far” ;)

If performance was ONLY measured in FLOPs then, you would be making a point.

However, in the real computing world, this does NOT equate to being faster.

The majority of software code depends on fast integer based calculations, not floating point calculations.

Also, the previous generation CPUs you are comparing are PowerPC based architectures that are primarily floating point based designs. So without even adding in the GPU, the base CPUs had very high FLOPs performance; however, this was a handicap as they had much slower integer based operation performance.

Umm the market decides, and they clearly decided theyw ere a waste..people dont buy vonsoles for voice (Which Ps4 has but didnt force it through an over priced peripheral). Most other thigns PS4 can do, including many thigns better, where is MS share play? PS now? Still cannot even take screens shots with X1...Ps4 install times and instant play go....Xbox was designed around media, people buy game consoels for gaming features....You are the minoroty, the sales speak for themselves.

We live in an era phones, Smart tvs can do all that stuff, cramming it in one set top box was cool in the 90's.. MS is out of touch as usual. If not for windows monopoly they's be irrelevant decades ago.

Again, the market decides, and they decided.....what you think is irrelevant. No one buys a consoel for snap, ordering dominos, vocie commands.
 
@NETAVENGER


Software gains happen to every console not just X1, Ps4's dev kits are also constantly improving, and no still most games have better resolutions and performance on PS4....You cannot over come weaker hardware with Softwate.....You are dilusional, X1 will improve,...but so will PS4, the hardware gap remains.

Where does x1 maintain more consistent frames???? Total BS, show me links of x1 games having better FPs at the same frames??? Even on lower resolutions s4 had more effects and better frame rates. Google digital foundry....You sound like you are dilusional.

You are the one that clearly doesn't understand fact or tech. ps4 is more powerfull , that is not going to change.

About the same problem they had and Germans in WWII with their submarines who attack the alleys merchant fleet. Due the SUDDENLY technological advance of alleys submarines anti measures, German generals suggest retreat and give time for technological advance of the submarines. Hitler decides to keep hit and ignoring the causalities. The end was alleys control the Atlantic. After that, alleys take the Germans strategy and hit the Japans merchant fleet. Japans they didn’t hit merchant ships because of Bushido code... What Microsoft can do? IF they believe in market must develop an exclusive and really outstanding graphic engine (MS is software company) for the X1 and give it for FREE to developers or if don’t believe in market must drop the price of X1 and keep improving the efficiency of all the peripherals systems of X1 and maybe later unofficially remove the copy protection.

Umm... pretty cool article but people aren't buying PS4's over a XB1 because of the graphics.

Are you really touting share play as an awesome feature which requires you to buy their failing handheld to get it to work? PS Now for streaming games, not a fan of streaming games, we have enough issues with trying to get consoles to go digital and bandwidth limits and data caps in the US. Adding ANOTHER service that eats away at your data just so you can play 10-20 year old games is not high value IMO. Give me something like EA Access, which of course I subscribe to and which Sony does not have, instead of something like PS Now.

Plus I would much rather have a reliable online experience, Sony's network has been horrible these past few months, with hacks and tons of downtime, they simply cant handle how well the system is selling it seems and I for one would be pretty pissed off if all these new online games I'm buying right now werent working the way they were supposed to because PSN is down yet again.

As for Screenshots, its coming in the January update most likely, which brings me to another point, the OS and update schedule from MS are far and above anything Sony is doing, I've already got external storage support, full media playback support with any file type, even the PLEX app to use with my network media set up. MS has been changing and adding features on a constant basis, while Sony sits and spins its wheels on still missing options. Starting a game right away during install doesnt take precedence over suspending my game and doing something else at any time, I can wait for a bit till my game is installed, its been that way on the PC forever now so why does it have to be instant gratification all of a sudden?

I dont deny that Sony is doing great and the PS4 is what the market is choosing (I will be putting one next to my Xbox One down the road trust me), but dont bash what you dont own or seem to have no clue about, without MS and Nintendo, Sony wouldnt have any competition which means what they did with the PS4 to make it "better" for consumers wouldnt have even happened, competition is good my friend, quit wishing the doom of other consoles and get past this fanboy nonsense

The weaker hardware on the xbone might really change some plans later on. In the end of each consoles life they came up with games that pushed the consoles to its utter limits. if the xbone reaches that limit much sooner then we're in for a new xbox early I guess.

Best bet for M$ is to bring out phenomenal games now to outclass Sony. Gotta say the Halo remastered collection might just be that. From all the HD re-releases this is probably the finest. So maybe it turns out to be the best thing for gamers. M$ got to make up for its shortcomings, and since they got the money to they may will.

Project Spark may hold great potential. Arguably the best shooters are available for xbone with Halo and exclusive CoD deals + the multi platfrom ones. Their racing games ain't haunted with problems like Driveclub. They got a bunch of strong IPs as well and most once ow so successful playstation exclusive games are now also on xbone. Sunset Overdrive is the new Ratchet & Clank and exclusive to xbone. Fantasia with Kinect is said to be amazing...

I'm much more of a Playstation fan than xbone but I gotta say they ain't in such a bad position.

Right now the weaker hardware doesn't seem to be much of an issue really. The noticeable difference in graphical fidelity between 768p 900p 1080p is so small its almost redundant. I thought that playing games in 4K thanks to DSR on PC might be a huge change but turns out neither was that. Same with the example pictures here, I can barely notice a difference in graphical fidelity.

Just a little theory of mine.

It's often hard to care about resolution differences beyond 1 megapixel when you're more than a few feet away from the display. just how eyesight works
 
Great article and dead on in terms of what the hardcore expect out of a new console. We want power, power, and power. However, there's an error... the Xbox 360 was more powerful than the PS3. Multiplatform games ran smoother on 360. I have played all Naughty Dog games on PS3 and you can't say they look better than the Gears of War series on 360. (Keep in mind that The Last of Us cut-scenes are pre-rendered video).

And you can't compare one games graphics to another, for console comparison.

This causes time constraints and sometimes you cannot expect programmers to have enough time to get acquainted with new things and even with these consoles being very close to PC's its still going to take time to get used to programming on these devices especially with curve balls like eSRAM.

Actually it is BECAUSE these consoles architecture is so close to PC's that developers will get the hang of eSRAM much sooner than later since the vast majority of studios are well versed in writing code for X86 architecture. We just haven't seen many of them properly use eSRAM because so many recent games have either already been delayed due to both the PS4 and Xbone being under-powered, and because of contractual release deadlines with publishers.

And while I know some of you will bristle at my assertion that these consoles are under-powered, sometimes the truth hurts. Neither console has the ability to run the latest games at 1080p with proper anti-aliasing, tessellation, and anisotropic texture filtering. The latter two just aren't utilized, and anti-aliasing is almost always crappy post-process anti-aliasing like FXAA or Temporal AA. Both do a fine job of destroying texture detail and create that all too common Vaseline effect. Additionally, shadow resolution and filtering is quite poor (notice how blocky shadows are in TLOU remastered when enabling 1080p/60?), LOD suffers, as well as ambient occlusion.
Don't believe me? Look how horrid the shadows are when TLOUR has 60fps switched on. http://cdn2-www.craveonline.com/assets/uploads/2014/07/TheLastofUsRemasteredComparison01.jpg
That is a direct result of not enough GPU power. ugh... http://cdn1-www.craveonline.com/assets/uploads/2014/07/TheLastofUsRemasteredComparison03.jpg

I had initially planned to purchase a PS4 back in early 2013 before the specs were released because I really liked my two PS3's (My original FAT died a few years ago), but I scrapped that idea as soon as I found out they were using an AMD APU designed for laptops. That $399 money was much better spent on a new GTX 780 Ti (newegg) that when overclocked to 1200mhz cranks out a massive 6.8 tflops. Yep... that's 3.7x more GPU power than a PS4.

The whole article is based on the mistaken assumption that the vast majority of consumers care about infinitesimal differences in graphics. Maybe it matters to hardcore gamers and tech enthusiasts but most people won't notice the difference. They'll just look at the console's price and its game library.
 
Price did not matter to me when I bought an Xbox One, but availability of games did. I also bought a PlayStation 4. The Xbox One had only very few Games in the beginning and only certain types of games. I think a lot of gamers look at game availability.
My Xbox one sat unused in the corner for 6 months as there was not even a Pinball game for XbONE.
 
I don't think the RAM is the single point of failure for the console's success.

Quite frankly, both the X1 and the PS4 are significantly underpowered for a 2014 release. Hype can only push your product so far and it seems like a common sentiment that these "next gen" consoles are underwhelming at best.

The fact that nearly all developers are unable to hit the most basic 1080p @ 60fps is a pretty good indicator.

Fun fact: upwards of 95% of PS4 games run at 1080p, 75% of those also run at 60 fps. (Via IGNs list of rendering resolutions)

The X1 has it quite a bit worse though, but I don't remember the exact stats for it.

There are multiple mistakes in this article. The PS4 not only has more memory bandwidth but is all around more powerful. More shader units, stream processors, ect.

In addition , near the end the author states that DDR5 memory would give the PS4 and Xbox one equal footing. It's Pretty bad to not know the difference between DDR and GDDR. GDDR5 IS DDR3 modified for high memory bandwidth. It's problem is that it has high latency. This means that games that load and unload data allot (open word) will have issues on the PS4.
 
I agree except for this, Even if they did change the Memory System to use DDR5, the GPU itself is considerably weaker:

The author's point was that if they opted for DDR5, they wouldn't have needed the eSRAM at all, which would have made space on the die for the exact same GPU configuration as the PS4.
