AMD's Rx 300 series line-up is largely a re-brand (with greater vRAM) of older GCN graphics cards, except for the high-end Fiji GPUs. While there's already some low-end parts in the R5/R7 300 series, it seems another one may be coming.
Recently there was a question by a Phoronix reader whether H.265/HEVC GPU-based video decode would be supported by the new AMDGPU driver stack on supported hardware. There is indeed the support in place with the latest Git of the open-source AMD Linux driver code.
AMD has published the initial patches for supporting the "Fiji" GPU with HBM memory, a.k.a. the new Radeon R9 Fury graphics cards, by the open-source "AMDGPU" Linux driver stack.
The AMDGPU scheduler patches published this week show more AMD developers involved than once was for the open-source AMD Linux driver stack.
Alex Deucher ended out the month by releasing thirty-one patches that implement a GPU scheduler for the new AMDGPU kernel DRM driver.
Earlier this week I delivered my initial benchmarks of the new AMDGPU Linux driver stack for supporting the AMD Radeon R9 285 "TONGA" and all new/future GPUs like Carrizo and Fiji. The new AMDGPU kernel driver is present in the upcoming Linux 4.2 kernel while on the user-space side there's separate code branches required for libdrm and Mesa. Fortunately, it looks like that work will be merged soon.
Continuing on from yesterday's first Linux review of the AMD Radeon R9 Fury, here are some more Catalyst Linux benchmarks from this $550 graphics card.
The OpenGL 4.1 patches for RadeonSI have now landed in Mesa Git master!
Since the Linux 4.0 kernel there has been DisplayPort audio support for the open-source Radeon driver. That DP audio handling came after a big rework to the audio code in the Radeon DRM kernel driver. A half-year later it looks like all the audio code is now cleaned up and ready.
As an update to last week's article and for those not following me on Twitter, the R9 Fury graphics card is running right now on Linux. The long-awaited AMD Fiji Linux test results are now imminent.
The latest OpenGL 4+ activity in Mesa this week is a Saturday commit landing another OpenGL 4.5 extension for AMD's RadeonSI Gallium3D driver for GCN graphics processors.
The news today of OpenGL 4 finally being accomplished in Mesa/Gallium3D is quite ironic and memorable as this day five years ago was when the R600 Gallium3D driver reached the milestone of being able to run glxgears on AMD hardware.
In the middle of the night I got an auto-notification... The Radeon R9 Fury is finally in-stock! Few minutes later, this Fiji HBM graphics card was ordered for some Linux testing. We'll have out the first major AMD Fury graphics card tests under Linux in the next few days.
AMD reported their 2015 second quarter results yesterday. As expected, they didn't look good.
Marek Olšák on Sunday sent out his latest patch series with the last of the EGL 1.5 bits for those on Linux using this modern interface over GLX.
I'm in the midst of a new large open-source and (separately) closed-source NVIDIA/AMD Linux graphics card comparison on the latest drivers as part of an upcoming Radeon R7 370 Linux review and to be followed by R9 Fury Linux benchmarks. However, for those interested in the Catalyst 15.7 benchmarks on Linux, I ran some quick tests with a Radeon R9 285 and R9 290.
Alex Deucher sent out twelve new patches just minutes ago for the AMDGPU DRM driver. The AMDGPU driver was merged for Linux 4.2 while these patches provide new features/functionality and thus will not be merged until Linux 4.3.
Yesterday's Catalyst 15.7 for Linux driver update turned out to be a fairly nice driver update. Tests are still running but the new features and performance improvements are certainly welcome.
The Catalyst 15.7 Linux graphics driver was just released, one day longer than anticipated.
AMD announced the FirePro S9170 this morning as the first server graphics card with 32GB of memory for high performance compute.
I'm in the process of running open-source RadeonSI Gallium3D tests on the new MSI Radeon R7 370 4G graphics card. That initial Linux review of the AMD Radeon R7 370 with the open-source driver will be published later this week (still waiting on an updated Catalyst driver for those proprietary driver tests). However, as an excerpt of the Gallium3D testing, here are results from some AMD graphics cards with Counter-Strike: Global Offensive and Team Fortress 2.
It's expected that today AMD will be releasing an updated Catalyst (v15.20) Linux graphics driver. Aside from Radeon Rx 300/Fury graphics card support, what do you hope is part of this new driver series?
AMD yesterday issued a warning over their second quarter guidance that they expect them to come in below expectations. Things aren't looking good with their stock price being down by another 16% so far this morning.
For those that follow me on Twitter know I've started testing the MSI Radeon R7 370 4G graphics card as one of the new models launched by AMD last month. For this new (non-Fiji) graphics card, using the open-source graphics driver is the only choice on Linux right now.
While the Linux 4.2 kernel merge window isn't yet over, AMD developers already have amassed a collection of fixes for the Radeon and AMDGPU DRM drivers following the big DRM pull.
One week after the Radeon R9 Fury X launched at $649 USD with an integrated water-cooling solution, the graphics card remains in short supply and it's not clear when exactly this graphics card will better saturate retail channels. At this point, I've shifted my focused to the air-cooled AMD Radeon R9 Fury graphics card that will ship in two weeks and be air-cooled while costing $100 less.
Following the recent report that AMD is exploring splitting itself up or potentially selling off business units, there's now a rumor out there that Microsoft has set its sights on AMD.
This week AMD launched the Radeon R9 Fury X at $649 for this "Fiji" GPU with High Bandwidth Memory that's liquid cooled. The Fury X is AMD's strongest competition to NVIDIA in years, but sadly this high-end graphics card appears to be in very short supply.
David Airlie landed some of the OpenGL 4.x code he's been playing with for AMD's RadeonSI Gallium3D driver on the HD 7000 series GPUs and newer.
AMD's new 64-bit ARM Opteron quad-core development board coming out later this year at an "affordable" price has us quite excited since it was announced earlier this week at the Red Hat Summit. ARM has now revealed the first pictures of this board.
