You're forgetting FMA and the area taken by the IGP. The CPU could have 3.2 GFLOPS/mm2. Sandy Bridge's IGP has a compute density of 3.1 GFLOPS/mm2. And that's theoretical throughput. We know AMD's architecture only achieve half of the effective throughput of NVIDIA's architecture, and even the latter can have a hard time keeping the ALUs fed. So they're not all that far apart at effective throughput.

Those discrete GPUs are also all significantly larger so no point in comparing their absolute bandwidth. Try maybe GF106 instead, it has 57.73 GB/s (and 2.5 GFLOPS/mm2). Next take into account that the CPU has large caches so it doesn't have to go to RAM that often. And last but not least, the IGP is limited to the same bandwidth as the CPU anyway.

And if we take power consumption into account we probably have to halve the frequency to approach the power consumption of the IGP, which also halves the GFLOPS/mm2. But that's fine, the total GFLOPS of the homogenous CPU is still higher. And the extra area has already been paid for anyway to make the CPU capable of running everything other than graphics as well. So we're looking at about a 2x disadvantage in effective thoughput density, but it's not stopping software rendering from becoming a viable graphics solution.

Yes that's reality. By the time TSMC has mastered 28 nm Intel will be producing at 22 nm. And this gap isn't about the dissapear. But whether you like it or not, it helps the CPU to be good enough at throughput computing to take over the role of the IGP.

Some of these improve effective throughput so they're not a loss. Others are vital to make the CPU capable of running the O.S. and any application, and that's largely paid for already. In comparison the GPU is utterly worthless on its own. So you really can't look at throughput density alone to assess whether or not a homogeneous architecture is viable.

This site suggests otherwise: http://www.legionhardware.com/articles_pages/intel_core_i5_2500k_and_core_i7_2600k_sandy_bridge,14.html

AVX already features 3 operand instructions, today.

Crysis is a good starting point. Certainly way better than comparing theoretical throughput.

We should actually take future workloads into account as well. A CPU with FMA and gather/scatter can be used for a lot of throughput-oriented workloads the IGP would totally suck at. This adds value too. Even in combination with a powerful discrete graphics card, such a CPU would be much more interesting than a CPU without gather/scatter and an IGP which remains idle.

Anyhow, let's start with Crysis.

You appear to have missed that I was talking about the control logic. The average switching activity for the control logic of different (arithmetic) uops is practically the same.

So what I was trying to say is that you pay the price of higher power consumption, when effectively achieving higher throughput. Or put another way: there are times when a GPU could be achieving higher effective performance/Watt if it spent some power extracting dynamic ILP.

It only partially compensates the CPUs power consumption, but sufficiently to make a future CPU with FMA and gather/scatter capable of taking on graphics. Note once more that the area investment would be an issue for GPUs, but with a CPU it's already paid for.

I'm not 100% wrong. If I was, then the GPU with the highest possible dependent instruction latency was the most efficient at throughput oriented workloads. But we both know this leads to register starvation and thus low effective throughput. Clearly you can't conclude anything from latency alone.

So how much of this 8x latency difference you claim is actually due to ALU lantecy? Note that on a CPU even an integer addition and multiplication have different latency (1 and 4), due to forwarding. So you can't simply look at the smallest latency and say the CPU is massively latency optimized, to the point where it sacrifices lots of effective throughput. If an add took 4 cycles instead, would that make the CPU 4 times more throughput-oriented? Obviously not, so likewise GPUs that spend most of the latency outside the ALUs aren't that much more throughput optimized.

Or in other words, a forwarding network massively reduces latency but that doesn't mean it required proportional area or power. And some of it is compensated by enabling the use of a smaller register file, reducing the number of threads to schedule, reducing cache pollution, increasing Amdahl's speedup factor, etc.

Only incomplete or irrelevant conclusions can be drawn from looking at one data point alone. 30x higher dependent instruction issue lantency is not a feat by any means and can't be used to determine effective throughput performance.

The viability of software rendering for a CPU with FMA and gather/scatter is affected by many more aspects as a whole. Analysing the data in depth shows that the 'gap' is nowhere near an order of magnitude as you're trying to imply, and the value of a homogenous architecture is greater than that of a CPU+IGP. Plus things are converging as well.

Take care,

Nicolas
