Ask GN 28: HBM on CPUs, GPU Boost 3.0 Curiosities, & More Test Methods

By Published September 17, 2016 at 8:30 am

This episode of Ask GN (#28) addresses the concept of HBM in non-GPU applications, primarily concerning its imminent deployment on CPUs. We also explore GPU Boost 3.0 and its variance within testing when working on the new GTX 1080 cards. The question of Boost's functionality arose as a response to our EVGA GTX 1080 FTW Hybrid vs. MSI Sea Hawk 1080 coverage, and asked why one 1080 was clock-dropping differently from another. We talk about that in this episode.

Discussion begins with proof that the Cullinan finally exists and has been sent to us – because it was impossible to find, after Computex – and carries into Knights Landing (Intel) coverage for MCDRAM, or “CPU HBM.” Testing methods are slotted in between, for an explanation on why some hardware choices are made when building a test environment.

"Hey Steve, would you ever consider testing with lower end CPUs occasionally to see the affect that they have on your results in a more real-world scenario?

Not everyone is rocking an X99 system so I think occasionally taking new cards and putting them with say an i5 or the FX chips would be very helpful for people looking for help with purchasing decisions so that they don't buy a card that they for example cannot take advantage of.

I understand it's a lot of work though so I don't expect to see this anytime soon :P

Thank you in advance if you do read this?"

"As High bandwidth memory (HBM) being the fastest memory that exist (today) , will we ever see cpu with HBM in the future? Or I have this in mind but is there a possibility that we can see a HBM ram in the future? How does fast memory as HBM affect pc performance or what benefit can we see from fast memory.?"

"Hey Steve, amazing channel!

I was watching your corsair/msi sea hawk x benchmarks as well as your evga hybrid benchmark videos and I noticed that on the corsair/msi model (https://www.youtube.com/watch?v=hjiTUeqXNhE&t=4m36s) the GPU craps out for 1 sec windows after being endurance tested (over 1 hour mark). This does NOT happen to the evga model. Do you think this may be due to the evga model cooling the vram while the corsair model overheats??"

16:21 FD: "Hello Steve, great video as always.I was wondering whether or not a window on a case could significantly effect temperatures and if their material, along with the number of windows, made a difference. Also do full glass cases have an advantage or disadvantage when it comes to cooling? I know you don't review cases often but any insight would be much appreciated.?"

19:57 standuporshutup: "Seems like there's a lot of work put into this channel. How do you and everyone else still find time to game??"

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
