5Ghz Amd & Intel (speculation topic)

IPC, that's what counts ultimately for the performance crown.

Amd's road map makes me feel really good about IPC in the AMD camp over the next few years. There are no major architectural changes really, well none as big as the Ryzen departure from the previous lineup anyway, so all the space saved as the process shrinks over the next 3 years can go to improving IPC - well potentially anyway, would be great for AMD to keep the pressure on Intel, they seem to have a strong foundation to build on at least with Ryzen

We're talking about AMD overtaking intel in the future with optimisations. So far none of those patches have been able to help them do that so how will anything else being created now be able to?

Likely the only way this would happen is through multi-core optimisations, since AMD still has a core advantage on desktop despite Coffee Lake. Same as what happened to the FX series compared to Sandy Bridge etc. This assumes Zen+ will clock say 10% higher though, otherwise Intel's clock speed advantage is just not surmountable in most situations.

I doubt AMD architecture specific optimisations will put them ahead, it'd probably put them in line at best. It's down to compilers really, it inevitably takes time for a compiler to optimise well for a new architecture and it takes even longer for new versions of compilers to actually be used by developers.

You say that but I've just spotted the 8/16 thread 1700 is topping the CPU charts here.

The point being it tests cpu performance in games. Nobody is expecting people to game at 720p but rather give an insight on how it will perform with faster more powerful future gpus.
I thought this was common knowledge.

It's a common mistake for sure. While it does make the gpu less likely to be the limiting factor it also changes the cpu workload with extra draw calls etc, meaning you're no longer effectively testing gaming performance but rather the cpu load derived from the draw call implementation for the current gpu, giving you no advantage in telling how it'll work in future.

This can mean for example that it makes a big difference who's GPU you use and which graphics api is used even though you're 'not gpu bottlenecked' as people who use that fairly meaningless term would say.
 
I'm not sure people have understood those OC3D results.

Also, Ryzen using 4C/4T is killing Intel 4C/4T at the same clock (He's locked a 1700 down to a 4C/4T and the same as the Intel). What's up with that?
 
Could be due to how the motherboards handle disabling cores.
Technically a single-CCX Ryzen with no SMT would be the best case scenario Ryzen for gaming since you don't have the NUMA/cache thrashing or 2 threads contending for the same pipeline. Clock for clock a SMT-less, single CCX Ryzen should be close or on par with Broadwell.
 
A few other websites also tested the game too.

The first is ComputerBase.de the second is GameGPU.

They tried with a few instruction sets like XOP, ABM or FMA4 and they dropped all of them with Zen. It's possible they'll add some new instruction sets with future Zen iterations, but I wouldn't expect anything groundbreaking. Currently AVX512 seems to be the big step forward, but no consumer apps support it (barely any consumer apps support AVX2/FMA3 to begin with).

Just a fyi , ABM is still supported
 
Ryzen has pleanty of room to improve and given a few generations it will, the inter ccx issue will be improved and probably fixed alltogether, so that it is no longer a problem. The clock speed will rise and eventually make it to where it is comparable to Intel.

But the thing that is easily forgotten is Intel are there now and they won't sit still while AMD play catchup, I have no idea what they will do, but rest assured, now that AMD have a competitive chip, Intel won't rest on thier laurels like they have done for the last god knows how long.

It will certainly be interesting times ahead for the CPU industry.

Intel's answer to Ryzen will be in 2021 and Im excited to see what they can do. I'd like to see Intel return to the market with a true desktop design and put an end to offering overpriced Laptop and Xeons platforms to home users.

The question is how interested are Intel in the enthusiast market and will money men give the engineers the freedom.

The money Intel make from retail is pretty insignificant compared to other markets and I'd Intel will look at those markets first.

What is a true desktop design??
