Re: iMac Pro includes the A10 Fusion

The real question is: what can this be used for? The obvious is performing a role as a security coprocessor in a similar fashion as the T1 in the touch bar MacBook Pros. However, is that is indeed the primary role, why just not include the T1 itself? My guess is that it is a coprocessor for low powe...

Re: Vulnerable Minix system in Intel chipsets

This was never made entirely clear to me form those who found the exploit though Intel's documentation would point to...

Re: Kaby Lake Raja Edition [Kaby Lake-G] photographed

I'm actually most interested to see how much the onboard HBM2 boosts the CPU performance. Could be even more than the Broadwell i7-5775c. It won't help directly as the CPU side has no reason to access the HBM memory connected to the GPU. The HBM isn't a cache level for the CPU (though the HBM may b...

Re: Upcoming monitors

If you're fishing for upcoming announcements, you'll probably have to wait until after the holidays when CES is in full swing. Lots of stuff gets will be shown there for release later in 2018.

I guess it all depends on how long you're willing to wait.

Re: So is the sound card dead?

These are two opposing design goals, and any solution that 'splits the m...

Re: Let's party like it's 1999 and look at single-threaded x87 FPU performance

There is a good chance the performance jump from Pentium M Dothan to Core 2 Duo Wolfdale is the increase in L2 cache. With 6 MB on-die, that Wolfdale chip has enough to keep everything in cache. While per core cache sizes haven't increased that much since Wolfdale when looking at the entire cache hi...

You don't need DIMMs for ECC, there just isn't any market for ECC memory in laptops right now. (since laptops are virtually the only place SO-DIMMs are right now). If SO-DIMMS were the mainstream RAM package you would see a lot more. Intel is doing a push with mobile Xeons in the 25W space. These d...

Re: SO-DIMMS for Everything?

Regular sized DIMMs have the room to hold enough chips for quad rank, registered ECC memory for ultra high capacity. I think off hand that SO-DIMMs only have enough room for dual rank and registered with a bit of extended height. So in that regard, they wouldn't work in the service space where memor...

Nope but there are mini-DP options as you've pointed out. HDMI is shunned in this space for several reasons. The first is cost as there is a per port HDMI licensing fee so it is partially for cost reasons. Secondly is that DP/mini-DP support higher resolutions (up to 8K30 right now via DP 1.4). Thir...

I've heard conflicting reports. The common theme of the negative ones is that it is going to be purely an artificial limitation imposed by Intel.
