Nvidia plans Geforce GTX 275 against Radeon HD 4890

By on March 23, 2009, 7:39 PM
AMD is getting ready to update their graphics card lineup with the introduction of the RV790-based Radeon HD 4890 which we recently received and were able to confirm the specs. While no pricing information has been confirmed yet, the card is expected to debut on April 9 for about $250, and as mentioned over the weekend Nvidia plans to fire back that same day with the GeForce GTX 275.


According to reports, the new card is going to have the same amount of stream processors as the GTX 280 and GTX 285 (240) but it will have 896MB GDDR3 on a 448-bit memory interface. It is built around the 55nm G200b GPU and will boast a core speed of 633MHz as well as 1404MHz for the Shader and 1161MHz for the memory. Likewise, the company is aiming for a $229 to $279 price range for the card. It should be interesting to see how these two perform when they hit the bench we already have a Radeon HD 4890 in our hands and are expecting to get the GTX 275 soon.

"...Nvidia plans to fire back that same day with the GeForce GTX 295."Is this a typo? Do you mean GeForce GTX 275?

Typo indeed, fixed now. Thank you.Watch out for our Radeon 4890 review soon...

looking forward to the reviews since im planning on building a new rig

anyone else wonder why Nvidia wont,...or cant use GDDR5?

GDDR5... lol.

(4890 vs. GTX275)Not bitching, but please try to include some overclocking results this time... I know you don't agree with OC'ing reference models (if that's what you'll receive), but that's what most of us do.A noise (db) chart would also be nice.

and so would i!?

Also one more thing, I have had interseting results asking this, What do most of you people prefer? Nvidia or ATI? its more of a comparision thing i'm doing on forms from multiple websites to get a true statistic of what people prefer.

Use to be ATI now Nvidia. I like the lower temps and less power usage.

Green Team all the way!!

still running on a 4850. before that was a 1950pro then a x850 then a 9700pro then a 9200. before that was a geforce 2mx - damn fine card, great price point.nvidia have never hit the same sweet spot since imo.maybe one day, but right now i would not go near an nvidia - i dont need to spend when i can play at 1680x1050 at full details with my current card.

[/quote]I will make sure we include some overclocking results, thanks for the feedback.As for comparing against the upcoming GeForce, we should be getting a card soon but ultimately it's up to Nvidia to get it to us on time.

Thanks guys for all your replies, Although after gathering lots of opinions It turns out Nvidia are more popular although a lot of people have said they used to be an ATI fan or they have converted to ATI, either way I think everyone seems to implie they have already owned an Nvidia graphics card. Anyway thanks all.

GDDR5 is a marketing tool, its not actual existing technology.Its whats made me dislike AMD more and more the past year or so.

HUh...really Tengeta, cuz Qimonda , Samsung , and Hynix Semiconductor all believe it does exist, oh and so does JEDEC. So you should really love AMD now.GDDR5 (Graphics Double Data Rate, version 5) is a type of graphics card memory the standards of which were set out in the GDDR5 specification by JEDEC. GDDR5 is the successor to GDDR4 and unlike its predecessors has two parallel DQ links which provide doubled I/O throughput when compared to GDDR4. GDDR5 SGRAM is a high performance dynamic random-access memory designed for applications requiring high bandwidth. GDDR5 SGRAM uses a 8n prefetch architecture and DDR interface to achieve high performance operation and can be configured to operate in x32 mode or x16 (clamshell) mode which is detected during device initialization. The GDDR5 interface transfers two 32 bit wide data words per WCK clock cycle to/from the I/O pins. Corresponding to the 8n prefetch a single write or read access consists of a 256 bit wide, two CK clock cycle data transfer at the internal memory core and eight corresponding 32 bit wide one-half WCK clock cycle data transfers at the I/O pins.Qimonda, a spin-off of Infineon, has demonstrated and sampled GDDR5 [1], and released a white paper about the technologies behind GDDR5 [2]. On May 10, 2008, Qimonda announced volume production of 512 Mib GDDR5 modules rated at 3.6 Gbit/s (900 MHz), 4.0 Gbit/s (1 GHz), and 4.5 Gbit/s (1.125 GHz).[3].Samsung had announced plans for the transition to GDDR5 by the beginning of 2008 [4]. It had since announced that it had developed GDDR5 memory at 6.0 Gbit/s at 512 Mib density.[5] On February 17, 2009, Samsung announced a 7Gbit/s 1Gb density part, allowing up to 28.2 GByte/sec bandwidth.[6]Hynix Semiconductor has introduced the industry's first 1 Gib GDDR5 memory. It supports a bandwidth of 20 GB/s on a 32-bit bus, which enables memory configurations of 1 GiB at 160 GB/s with only 8 circuits on a 256-bit bus.[7]besides that, if GDDR5 was imaginary, dont you think Nvidia would be all over that like a wet blanket?[Edited by red1776 on 2009-03-25 20:17:36]
