Digital Foundry: Why DX12 is a gamechanger for PC (and AMD!)

[ethomaz]

If I'm interpreting your statements correctly, you saying that the physical cores of the AMD CPUs aren't the reason for the increase from Direct X 12 and that the HT from Intel processors kept them ahead in performance.  I then rebuttled that's not the case since software favoured Intel's setup due to little multithreading in most applications.  I'm also not denying per core performance is in Intel's favour.

The DX12 have nothing to do with the IPC of the Intel/AMD CPUs... the Intel CPUs is way ahead what AMD have... the HT is just a trick that makes the parts of what is not being used in core to be used in another thread... so in some cases you have a 30% increase in multithreading tasks (the real name of the HT is SMT - simultaneous multithreading).

Said that... any free up of the CPU made by DX12 will works both Intel and AMD.

Thanks Etho.

I can't say that I've run into an issue with my cpu. Not really sure it would have been worth the extra cost for an intel.

Mostly worth it if you are emulating.

I know full well what Hyper Threading is, it's virtualization of the cores to split it.  It literally doesn't work without the OS coded for it.  That's not what I was discussing.  I was discussing AMD getting a bigger boost from Direct X 12 because the software is properly multi threaded, my hunch.   Most user grade intel processors are 4 cores, current AMDs are 6+.  Though the i7s with the hexa and octa cores will probably destroy the benchmarks for Direct X 12.

Well yes. 
Intel is still ahead though, even without HT.

Per core yes, 3 threads, it won't be ;p

Intel has a better IPC / Architecture than AMD.

But I won't lie because I think the biggest advantage Intel have over anybody else in the market is the manufacture process... they have the best tech to create processor in the world (IBM have a pretty good tech too that AMD/GF bases to produce processors).

While Intel is already on 14nm... AMD/GF is having trouble with 20nm and 16nm.

This is one of the biggest advantage of Intel.

Yeah, AMD fired all their top end engineers which led to their sub par processors.  I just want a processor revolution. Processors haven't really progressed, they sort of stagnated.
