Intel Core Ultra 7 155H underwhelms in leaked benchmarks ahead of official launch

[Huesane]

Bottom line: Leaked benchmarks for Intel's upcoming Core Ultra 7 155H Meteor Lake processor have arrived, bringing with them plenty of interest. Unfortunately for Team Blue, they reveal some underwhelming results. While the chip does display potential with its integrated graphics capabilities, aspects such as CPU performance and battery life are causing concern, particularly when compared to AMD's Ryzen 7 7840HS.

Slated for an official launch on December 14, this isn't the first time we've seen leaked details regarding Intel's Core Ultra 7 155H, part of the Meteor Lake mobile series.

The latest information comes from some pre-launch tests conducted by Bilibili user Corbcas, who revealed a mixed bag of results.

The 155H does shine when it comes to integrated graphics, scoring 3,077 points in the 3DMark Time Spy Graphics test, outperforming even AMD's Radeon 780M graphics from the Ryzen 7840HS. This achievement is notable, considering the iGPU's strong presence in high-end gaming handhelds. However, the CPU performance tells a different story: the 155H's CPU results in Cinebench R23 are definitely less impressive, especially when stacked against the Ryzen 7 7840HS.

Component	Intel Core Ultra 7 155H	AMD Ryzen 7 7840HS
3DMark Time Spy Graphics Score	3,077	2,749
Cinebench R23 Single-Threaded Score	1,483	~1,800
Cinebench R23 Multi-Threaded Score	12,085	~16,000
Power Consumption	~40 watts	~35W

The Intel chip's single-threaded and multi-threaded scores fell short of expectations, a surprising turn for a brand known for its CPU prowess. As AMD is gearing up to launch its Ryzen 8000G APU, this is a significant point for those looking to pick up a new machine soon.

Power consumption of the 155H, at around 40 watts in both Cinebench R23 and Time Spy tests, is on par with its competitors, with no giant leap in efficiency. In battery life tests, including standby, video playback, and web browsing, the 155H lagged behind the Ryzen 7 7840HS, which delivered significantly better battery performance.

The benchmarks also highlighted inconsistencies in the 155H's CPU clock speeds, which could be a factor in its varied CPU performance. During the Time Spy test, the chip's clock speed fluctuated, occasionally peaking at 4.5GHz but also dropping to around 3GHz. These stuttering results are sure to put a speed bump in Intel's roadmap for its CPU series, including the upcoming Arrow Lake, Lunar Lake, and Panther Lake.

While the GPU performance of the 155H is a step in the right direction, the CPU results and battery life leave something to be desired. The final verdict of the chip's real-world capabilities will only be clear after some hands-on testing. But for now, it seems the laptop variant of Meteor Lake CPUs could also be heading in a disappointing direction like its desktop cousins.

Intel last bastion was mobile. With those figures, they might lose this one to in 2024.

This seems to be worst than the 11th gen fiasco.

3DMark Time Spy Graphics Score
3,077 / 2,749 = 1.12

Cinebench R23 Single-Threaded Score
1,483 / 1,800 = 0.82

Cinebench R23 Multi-Threaded Score
12,085 / 16,000 = 0.75

Power Consumption
40W / 35W = 1.14

How's it priced? AMD is no longer the budget option. Zen4 is great but the price is absurd.

"During the Time Spy test, the chip's clock speed fluctuated, occasionally peaking at 4.5GHz but also dropping to around 3GHz."

That's normal during the Graphics tests. Obviously not for the CPU tests but as it's a crap phone video screengrab, judgements about about clockspeeds is irrelevant because we don't know what's being tested.

That CB R23 score makes no sense, a 13600K/14600K scores about 1800 ST and 11500 MT when limited to 35W. A Meteor Lake CPU with the same core count shouldn't be getting the same score unless it's throttling.

There seems to be another leak that shows 15500 MT, which is a lot more in line with what would be expected from a new CPU focused on lower power.

Im glad that intel finally got that GT2 iGPU working, AMD needs some competition to finally progress (and for those who will froth at the moth about NUH UH, let me remind you we are now on the third generation of rDNA APU with no increase in GPU core count, the last time we got an increase was when XE came out). The rest feels very meh though.

Or it very well could be that intel still cant get power consumption under control for mobile, and it is throttling.

This score would make the 13700H faster than the 155H at the same power. I think it's more likely that they used a notebook with subpar cooling solution and it thermal throttled during the test.
Jarrod's Tech testing on the 13700H at 40W shows it getting 12230 MT, and while I couldn't find the score for ST on CB R23, it seems like it would be about the same as the 7840HS based on the other tests.

The release is just days away. let's wait for real benchmarking from the likes of this website and others. As though anyone gives a damn about geekbench scores or cpu-z results.

If Meteor Lake can match Raptor Lake but use at least 35% less power it's a good first gen effort. If not they are in a huge spot of bother in 2024 in laptops.

 

[Kashim]

I've said this before, but I'll say it again; when a big player like Intel starts adding words like "Ultra" to the end of their naming schemes in an attempt to one-up the competition it is never a good sign. It's like when someone goes around constantly telling everyone how smart they are. Smart people don't need to constantly proclaim they're smart and a good product speaks for itself without nonsense monikers like super/ultra/hyper/etc.

 

[Watzupken]

I think we should wait for official reviews before concluding. This is what Pat said, their "Zen moment". Hopefully this is not turning out as a Ice Lake moment, or worst, Cannon Lake moment. I do feel that Intel is charging too much for what is mostly just cheaper E-cores. And I seriously have no interest in buying anything more than 8 "E-cores"...

These are expensive to produce (new lithography, complex design, advance packaging)... furthermore Intel reserved the "Ultra" name for Meteor Lake - this is another indication that they won't be cheap.

Ultra has nothing to do with comparing their chips to Apple m series chips?
