Re: Eclipse on August 21

Re: Projectors - need advice

I have a bit of experience with projectors. You mention latency as a feature you want, and well you're going to get it, lots of it. Latency is typically very high on a projector vs. LCD display due to additional scalar electronics. It can handle simple things like front/rear and table/ceiling mount ...

Re: OMG ThreadRipper Review Roundup

The DAW comparison is both unique and relevant, for example, though Jeff kind of spoiled it on Twitter - Threadrippa ain't for audio workstations. Which is fine, because Avid only endorses Intel builds anyway. I like the DAW Bench tests as well. I don't think you can say that Threadripper isn't sui...

Re: Coffee Lake Not Supported by Intel’s 200-Series Motherboards?

The thing is that when Intel dropped their tick-tock cadence into a three step cadence, the implication was that socket infrastructure would follow suit and be supported for three generations. Thus existing socket 1151 motherboards would support Coffee Lake/Cannon Lake with a firmware update. The ge...

Re: Looking for thunderbolt 3 PCIe chassis

The Sonnet Echo Express III looks to be using the effective link speed converted to bytes with overhead removed. It is a very odd way of doing this as that figure is far from guaranteed due to other devices on the chain and if DP is encapsulated alongside PCIe.

Re: The Threadripper: THERE. ARE. FOUR. DIES!

With Four dies present and being based on pretty near the same socket as EPYC, the question then remains... could they enable 4-cores on each and have 2-dimms per core for 8 channels of memory? Perhaps in the future and enable more cores? Maybe an upgrade next year with Ryzen 2 or 7nm late in 2018?...

Does this game become wonderfully broken when you cross class skills like Diablo 2 did? That was the real fun: taking a sorceress, give her elemental damage paladin auras from items, then another item to shape shift her into a were bear like a druid for the most powerful melee build in the game.

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...

A little CPU humor...

On a 16 core system, there could be several patterns of maximum sepa...

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...
