Re: Dumb idea/thought experiment

The idea of AMD adding HMB on package has been floating around for awhile. Probably won't happen until cost/yields are ready for mainstream production runs. However, HBM is a bit of a power hog for mobile due to it being consistently active. The similar technology for the mobile market is known as W...

Re: AMD is back with a vengeance -

Anything that's memory latency or bandwidth bound that doesn't fit in GPU memory. In my line of work, that's basically all of the problems we run (physics simulations). They tend to sweep all of memory evenly, and we buy machines for memory capacity and bandwidth, for the most part. The cache hiera...

Re: Symmetric Multi Turboboost

A little CPU humor... You would think that AMD instead of just boosting one core, could find a way to turbo up several cores in a pattern that maximizes their die separation so they could run hotter and spread out the heat better. On a 16 core system, there could be several patterns of maximum sepa...

Re: Skylake X: Bye Bye Rings, Hello Mesh

Re: Skylake X: Bye Bye Rings, Hello Mesh

AMD's reference to HBM as a cache in their literature is due to the GPU fitting comfortably into a coherent memory schema. If Vega can utilize an Infinity Fabric link to an Epyc CPU socket as some rumors are to be believed, then they would be coherent with each other. The GPU have full access to sys...

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...

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'?...
