Gaming Performance: iGPU

Despite updating the main bulk of our CPU test suite for 2023 and beyond, we've not had a chance to test every integrated graphics chip in our stack of CPUs. As a result of this, we've included limited results for our iGPU-based gaming tests, although it is more than enough to get to grips with improvements in Raptor Lake performance.

As a reminder, We are using DDR5 memory on the Core i9-13900K, the Core i5-13600K as well as Intel's 12th Gen (Alder Lake) processors at the following settings:

  • DDR5-5600B CL46 - Intel 13th Gen
  • DDR5-4800 (B) CL40 - Intel 12th Gen

All other CPUs such as Ryzen 5000 and 3000 APUs were tested at the relevant JEDEC settings as per the processor's individual memory support with DDR4.

For both 13th and 12th Gen Core series processors, Intel is using the Xe-LP based 770 HD graphics processor. This means the overall integrated graphics performance between the two is almost identical.

In our integrated (iGPU) graphics testing, the power of Intel's Raptor Cove cores combined with more E-cores does show a distinct, but negligable advantage when using Intel's 770 HD graphics. This advantage is clear in Final Fantasy 14 where more cores and more CPU power are advantageous for performance.

Looking at the iGPU performance of both the Core i9-13900K and Core i5-13600K in our other tests, the Core i9 performs best out of Intel's chips, but in games where graphical power is required, the AMD 5000 series APUs do come out best. The Core i5-13600K also performs marginally worse than the Intel Core i9 12th Gen series, but this is to be expected.

    Correction: the 12600k is 6P+4E - table on first page

    I am hoping for an high frequency 8 core i5 with zero ecores and high cache. It's would be a gamer sweet spot, and could counter the inevitable 3d cache Zen 4.

    big.LITTLE isn't going away. It's in a billion smartphones, and it will be in most of Intel's consumer CPUs going forward.

    Just grab your 7800X3D, before AMD does its own big/small implementation with Zen 5.

    Honestly, I'm underwhelmed by Intel's current big.LITTLE setup. As near as I can tell, under load the E cores are considerably less efficient than the P cores are, and currently just seem to be there so Intel can claim multi-threading victories with less die space.

    And with the CPU's heat limits, it just seems to be pushing the chip into thermal throttling even faster.

    Hopefully future big.LITTLE implementations are better.

    Meteor Lake will bring Redwood Cove to replace Golden/Raptor Cove, and Crestmont to replace Gracemont. Gracemont in Raptor Lake is the same as in Alder Lake except for more cache, IIRC. All of this will be on "Intel 4" instead of "Intel 7", and the core count might be 8+16 again.

    Put it all together and it should have a lot of breathing room compared to the 13900K(S).

    8+32 will be the ultimate test of small cores, but they're already migrating on down to the cheaper chips like the 13400/13500.

    Yes it does seem backwards that the more efficient architecture is in the P core. Reducing power consumption for light tasks seems better to keep it on the P core and downclock. I don't see the point of the "e" cores as effiency, but rather academic multithreaded benchmark war. Which isn't serving the consumer at all.

    E is still useful, as you get 8/8 cores in space where you could cram 2/4. I agree E for efficiency should be B as background to make it clearer what's the point. They are good for consumers as they offer all the high speed cores for main process, so OS and other things dont slow down.
    I am not sure if you followed, but intel cpu's literally doubled in power since they appeared, and at ~25% utilization, cpu's halved power usage. What you should complain about is bad software support, as this is not something that happens in the background.

    I don't think you are fully grasping the results of the benchmarks. Compute/Rendering scores prove that e-cores can tackle heavy work loads. Often trading blows with AMD's all P-Core 7950X, and costing less at the same time. AMD needs to lower all prices immediately.

    That's an oversimplification actually, P-cores and E-cores are both efficient, just for different tasks. The main efficiency gain of P-cores is it's much much faster than E-cores for larger tasks. Between 3 and 4GHz, P-cores are so fast they finish tasks much earlier than e-cores so total energy drawn is lower. But E-cores are efficient too, just for simple tasks(at low clockspeeds). Below 3GHz and above 1GHz, e-cores are much more efficient, beating P-cores in performance while drawing less power.

    Big.LITTLE is hard to do, and ARM took ages and a lot of optimization before phone CPUs got much benefit from it.

    The problem of the LITTLE cores not adding anything in the way of power efficiency is well-known.

    I'm saddened that Intel is dropping their own winning formula of "race-to-sleep" that they've successfully used for decades for aping something objectivly worse because they're a little behind in die shrinking.
