[H]ard|OCP have been examining the generational performance differences between GPUs, starting with NVIDIA and moving onto AMD.  In this review they compare Hawaii GCN 1.1, Fiji GCN 1.3 and Vega10 GCN 1.5 on a wide variety of games.  AMD is a more interesting case as they have made more frequent changes to their architecture, while at the same time tending towards mid-range performance as opposed to aiming for the high end of performance and pricing.  This has led to interesting results, with certain GCN versions offering more compelling upgrade paths than others.  Take a close look to see how AMD's GPUs have changed over the past five years.

"Wonder how much performance you are truly getting from GPU to GPU upgrade in games? We take GPUs from AMD and compare performance gained from 2013 to 2018. This is our AMD GPU Generational Performance Part 1 article focusing on the Radeon R9 290X, Radeon R9 390X, Radeon R9 Fury X, and Radeon RX Vega 64 in 14 games."

A teaser on executive migrations and GLOFO's refusal to shrink from their strengths

Subject: General Tech | August 29, 2018 - 01:10 PM |
Tagged: Jim Anderson, amd, lattice semiconductor, GLOBALFOUNDRIES

There will be a bit to talk about on tonight's podcast as we have seen two big changes in the industry this week.  Most recently Jim Anderson, the GM and SVP of AMD's Computing and Graphics section handed in his resignation to become CEO of Lattice Semiconductor.  The 35 year old FPGA company has had quite a history, from filing for Chapter 11 to grabbing IP from Silicon Image to having their purchase by a Chinese corporation blocked by the US Government.  You may have never heard of them but there is a good chance you have seen or used some of their products.  It will be interesting to see what this means for both companies.

The second big change comes from GLOBALFOUNDRIES and is right up Josh's 7nm alley.  They will be abandoning their 7nm process to focus on their 14 and 12nm FinFET as their CEO, Tom Caulfield stated that this move makes sense as many companies have no interest in the new and more expensive fabrication process.  This argument was undermined by AMD's immediately announced they will be moving the production of their next CPUs and GPUs to TSMC.  There are several other companies, one of which being ARM, who are also narrowly focused on moving to 7nm and beyond.  Intel has been quiet so far, for fairly obvious reasons.

"Anderson hails from AMD where he was senior veep and GM of the chip flinger's Computing and Graphics Business Group. He joined AMD in May 2015, following stints at Intel, Avago and LSI, and directly replaces Glen Hawk, who was interim boss and will remain as special advisor to the CEO until the end of October."

Sure you have GigaRays, but can you power 32 VMs per card? Meet the Radeon Pro V340

Subject: General Tech | August 28, 2018 - 01:21 PM |
Tagged: Vega, Radeon Pro V340, radeon pro, amd

The new Radeon Pro V340 is designed in a way we haven't seen from AMD in a while, with dual Vega 56 GPUs sharing the same PCB with 32GB of HBM2.  The card is not aimed at the same market segment as NVIDIA's new RTX cards, instead AMD is talking up its virtualisation abilities.  One card can support 32 VMs, which means AMD could have perhaps picked a better name, but that does not detract from this impressive ability.  This could position AMD to compete effectively against NVIDIA's GeForce Now game streaming service and offer their own service to allow you to play games over the net, independent of your own hardware.  You can check out the announcement video over at The Inquirer to see how AMD is planning on positioning themselves.

"Essentially squashing two Vega 56 graphics cards together, the Radeon Pro V340 sports 112 compute units and 7,168 stream processors. It also makes use of high-bandwidth memory totalling in 32GB of HBM2, which touts a bandwidth of 512GB/s"

We aim to find out

Back in April of this year we first took a look at the storage performance of the then-new X470 chipset for the 2nd generation of Ryzen processors. Allyn dove into NVMe RAID performance and also a new offering called StoreMI. Based on a software tiered storage solution from Enmotus, StoreMI was a way for AMD to offer storage features and capabilities matching or exceeding that of Intel’s mainstream consumer platforms without the need for extensive in-house development.

Allyn described the technology well:

AMD has also launched their answer to Intel RST caching. StoreMI is actually a more flexible solution that offers some unique advantages over Intel. Instead of copying a section of HDD data to the SSD cache, StoreMI combines the total available storage space of both the HDD and SSD, and is able to seamlessly shuffle the more active data blocks to the SSD. StoreMI also offers more cache capacity than Intel - up to 512 256GB SSD caches are possible (60GB limit on Intel). Lastly, the user can opt to donate 2GB of RAM as an additional caching layer.

We recently did some testing with StoreMI after the release of the 2nd generation Threadripper processor evaluation was out of the way, just to get a feel for the current state of the software offering and whether or not it could really close the gap with the Optane caching solutions that Intel was putting forward for enthusiasts.

Your Mileage May Vary

One of the most interesting things going around in the computer hardware communities this past weekend was the revelation from a user named bryf50 on Reddit that they somehow had gotten his FreeSync display working with his NVIDIA GeForce GPU. 

For those of you that might not be familiar with the particular ins-and-outs of these variable refresh technologies, getting FreeSync displays to work on NVIDIA GPUs is potentially a very big deal.

While NVIDIA GPUs support the NVIDIA G-SYNC variable refresh rate standard, they are not compatible with Adaptive Sync (the technology on which FreeSync is based) displays. Despite Adaptive Sync being an open standard, and an optional extension to the DisplayPort specification, NVIDIA so far has chosen not to support these displays.

However, this provides some major downsides to consumers looking to purchase displays and graphics cards. Due to the lack of interoperability, consumers can get locked into a GPU vendor if they want to continue to use the variable refresh functionality of their display. Plus, Adaptive-Sync/FreeSync monitors, in general, seem to be significantly more inexpensive for similar specifications.

MSI's B350I PRO AC, gone but not forgotten

Subject: Motherboards | August 24, 2018 - 04:15 PM |
Tagged: mini-itx, msi, b350, B350I PRO AC, amd, ryzen

The MSI B350I Pro AC is not a new motherboard but it is worth remembering for anyone looking to build a small system.  However [H]ard|OCP is teasing you a bit; the board was in stock when they started the review but has been discontinued very recently with the B450I Gaming Plus AC replacing it.  Why is it worth looking at, you may ask?  The board is a solid base to build a SFF system off of and will be selling at a discount if you can find it; so keep your eyes open and you might get it for a song.

"While we might be late to the party with a B350 review, we were running tests with it and were so impressed we thought we would put it through the full review process. MSI’s B350I PRO AC might just have been worth the wait. How does this inexpensive powerhouse fair against more expensive offerings?"

Vive la différence! Threadripper 2 on Linux and Windows 10

Subject: Processors | August 21, 2018 - 03:51 PM |
Tagged: 2990wx, threadripper 2, linux, windows 10, amd

Windows 10 is much better at dealing with multithreaded tasks but Linux has been optimized for both high core counts and NUMA for quite a while, so looking at the performance difference is quite interesting.  Phoronix tested a variety of Linux flavours as well as Windows 10 Pro and the performance differences are striking, in some cases we see results twice as fast on Linux as Win10.  That does not hold true for all tests as there are some benchmarks which Windows excels at.  Take a look at this full review as well as those under the fold for a fuller picture.

"Complementing the extensive Linux benchmarks done earlier today of the AMD Threadripper 2990WX in our review (as well as on the Threadripper 2950X), in this article are our first Windows 10 vs. Linux benchmarks of this 32-core / 64-thread $1799 USD processor. Tests were done from Microsoft Windows 10 against Clear Linux, Ubuntu 18.04, the Arch-based Antergos 18.7-Rolling, and openSUSE Tumbleweed."
