Raven Ridge will offer a CPU+GPU combo in AM4 packaging. It is due later this year.

Re: Skylake X: Bye Bye Rings, Hello Mesh

I wonder if the interposer used in HBM can be used to provide mesh or infinity link between modules in a package. Yes. Raja of AMD has dropped hints that that is the direction he's going for GPUs. Same principles for scaling the number of CPUs cores in a design. Intel also has their EMIB technology...

As mentioned in this thread, the Knight's Landing Xeon Phi uses this mesh topology the core's used in Knight's Landing are base...

Re: Personal Supercomputer, didn't know there was such a thing.

The idea of a personal super computer is not a new thing. SuperMicro and others have such high end systems support multi GPUs for Teslsa and/or Xeon Phi. I've even heard of mixed brand setups with nVidia Tesla + AMD FirePro or nVidia Tesla + Intel Xeon Phi to follow the idea of using-the-best-tool-f...

Hynix did state that there was a 2018 product using a 384 bit wide GDDR6 bus. After that, it was presumed that it was the GV102 following traditional iterations.

Any AMD part needing bandwidth is simply using HBM2.

Re: Volta TI Edition Musings

There were quiet a few minor differences between the GP100 and GP102. First off was the memory interface where GP100 uses HBM with an undisclosed number of ROPs. Between the higher bandwidth and purportedly more ROPs, this should give the GP100 better performance at higher resolutions. The other dif...

Re: Bad Intel Docs & Skylake X die size estimate

Actually, as the number of cores goes up then if all other metrics remain constant the "per core" metric for the chip goes down since there is a large "fixed cost" for things like the memory controller and I/O silicon that remain constant as the number of cores goes up. Higher c...

Re: Nvidia has been humping servers and it's ugly!

Might as well go full hump and make it a 4U chassis with proper ducts from the front rear directly to the GPU cards. Air intake at that time wouldn't be heated from the CPU/memory in front behind it. Taking a closer look, airflow in that thing is all messed up. The GPU cards exhaust out the 'front'?...

I'm actually rather impressed with those figures from the Sky Lake-E part. The larger L2 cache has a far greater performance boost than I was expecting. I'm still betting on a new on-die topology so that'd likely help as well. We're also not seeing Sky Lake-E's full potential as the Sky Lake-EP vers...

Those VISC guys did have real hardware to demonstrate that the principle did at least work.

Re: Looks like RyZen got caught cheating on benchmarks

If AMD went the VISC optimization path, it could cache the optimized code path as it generates the code dynamically to access that later. The result would be some drive controlled directory that balloons in size as more code is ran.

Re: Looks like RyZen got caught cheating on benchmarks

The most likely scenario is that the benchmark was doing some calculations and throwing the results away (e.g. saving the results in machine registers and not storing them to RAM before overwriting them with something else). The CPU noticed the calculations were pointless, and skipped them. This is...

Aiming for higher clocks isn't a bad thing as IPC gains, even on the Intel side, have been increasingly marginal.
