    Apple GPU performance projections

    Posted: 26 Jun 2020 09:12 AM PDT

    Apple is bringing their silicon to the big stage, and their CPUs are rightly getting a lot of attention. An 8+4 core A14 desktop CPU at 3 GHz clocks would crush anything AMD or Intel has on the market without substantially more cores. But what about their GPUs?

    How big?

    I suspect a desktop A14 could have 8+4 CPU cores and 16 GPU cores without pushing the die size particularly far, especially given the 5nm node shrink will give Apple some slack.

      A12 A12Z A13 A13Z (guess) A14 Desktop (guess)
    CPU Cores 2+4 4+4 2+4 4+4 8+4
    GPU Cores 4 8 4 8 16
    Die size 83 mm² 122 mm² 98 mm² ~140 mm² <250 mm²

    What would the performance of a 16 core A14 GPU be?

    Unfortunately, data is sporadic. There is no A13Z, the A12X has a core disabled, and cross-platform benchmarks are lacking. Plus this is well outside my area of expertise. But let's try.

    According to AnandTech, the A13's GPU is about 20% faster than the A12's. The A12 was much more than 20% faster than the A11, often closer to 50%. So let's assume that the A14's GPU is 25% faster than the A13's, or 50% faster than the A12's.

    The A12X (remember, one of the 8 cores is disabled), scored 197k in 3DMark Ice Storm Unlimited - Graphics. A 50% boost to an A14X gives us ~300k, about par with a notebook GTX 1060.

    If perfect scaling held, a 16 GPU core A14 Desktop would score ~670k. However, the median 2080 Ti scores 478k, so clearly perfect scaling doesn't hold. More sensibly, we might expect a 16 GPU core A14 to score about the same as an NVIDIA GPU with ~230% of a 1060's CUDA Cores, aka. ~2900 CUDA Cores. This is higher than a 1080, and about par with a 2080. We've not accounted for the 2080's generational IPC boost, but the numbers are so approximate that I'm willing to ignore it.

    Alas, Apple's GPUs, as with most mobile GPUs, favour 16 bit calculations, as opposed to the 32 bit calculations standard for other devices. Apple only describes the A12X as 'Xbox One S class', presumably because that's roughly what you get looking at their 32 bit performance, whereas I believe the benchmarks will measure 16 bit. Adjusting from the 32 bit baseline probably results in somewhere between a 1060 and a 1070, using a variety of hand-waving techniques.

    TL;DR

    Guessing Apple's scaled GPU performance is hard. A low estimate is half way between a 1060 and a 1070. A high estimate is rough parity to a 2080. Neither claim is obviously more correct to my inexpert eyes. Both guesses assume similar power budget per core to the A12Z, meaning all this power would come from a ~20 Watt GPU.

    I'm curious what other people expect.

    Is x86 a design failure?

    Posted: 26 Jun 2020 10:12 PM PDT

    Everyone is talking about the ARM vs x86 architecture. I know that ARM has simpler instruction design making it power efficient and easier to manufacture. x86 on the other hand, because of the design, it can run much more complex instructions resulting to power hungry and bigger die. I read that most of these instructions in arm are simple that it can run in one cycle unlike with x86, instructions are complex that it could take more cycles.

    So if I did get it right, the war between the two is between simple vs complex design. Now Apple is moving to ARM so maybe they have a chip that could potentially beat x86 in the future on the high end consumer processor. Who knows.

    I do like the idea of everyone moving to arm. We would see ARM motherboard much more common then our phone apps will also run in our desktop. Developers will now have only one source code for both maybe. No more headache for us.

    So anyway, does that mean simple design will always be much better? I wonder if intel has a ARM license and also making a processors for it now.
