AMD Develops New Linux Open-Source Driver Model 142

Posted by timothy
from the winds-of-change dept.
An anonymous reader writes "AMD privately shared with Phoronix during GDC2014 that they're developing a new Linux driver model. While there will still be an open (Gallium3D) and closed-source (Catalyst) driver, the Catalyst driver will be much smaller. AMD developers are trying to isolate the closed-source portion of the driver to just user-space while the kernel driver that's in the mainline Linux kernel would also be used by Catalyst. It's not clear if this will ultimately work but they hope it will for reducing code duplication, eliminating fragmentation with different kernels, and allowing open and closed-source driver developers to better collaborate over the AMD Radeon Linux kernel driver."

        Lower power consumption in better CPUs. Why choose AMD?

        The most recent generation of chips definitely has power issues, but it seems like you get a lot more bang for your buck with AMD. What can you get that is decent from Intel for $120? You can get a fairly decent chip from AMD for that.

          Hell, a 40$ APU from AMD beats anything Intel has to offer for almost twice as much, not to mention that even at that price the AMD has a decent GPU while the Intel has none at all.

            This is why I think AMD tends to be represented more in the DIY arena. Companies like Dell don't want to sell you a $150 CPU+motherboard upgrade. They want to sell you a $1200 PC. If you're going to throw away your old case, PSU, video card, RAM, hard drive, DVD drive, etc - then you might as well spend an extra $200 on the CPU.

            On the other hand, if you're only upgrading CPU+MB, and maybe RAM, then AMD makes a lot more sense. If my options are to spend $500 every 6 years on an Intel CPU+MB, or $150 every other year on an AMD CPU+MB, then I'll take the latter. I'll actually spend less money, and for most of the time I'll have a better system. Sure, the Intel system will outperform the AMD system in years 1-2, but the AMD system will outperform in years 3-6, and by a huge margin in the last two years. A CPU is a rapidly-depreciating asset, so it doesn't make a lot of sense to spend a lot of money going high-end - you're far better off buying something moderate and replacing it more often. Then Moore's Law will work for you, and not against you.

                What you fail to mention is the fact you could have probably built most if not all of an AMD 6 core system for the cost of the i7-860 alone, and if one were to go one notch down to the quads (which lets face it software just hasn't kept up with hardware and even more triple cores spend more time at idle than under load) then one could have easily built the entire system. The 8 cores were built just to say they could and frankly have never been priced competitively, no different than those 5Ghz chips they released not too long ago.

                My oldest boy has an AMD hexacore, 8Gb of RAM, a 1Tb HDD and an HD7750, the whole system ended up costing something like $375 after MIRs. It kicks ass at gaming, transcoding, hell it'll do anything your average user will be able to think up for a PC to do and do so quite well and cost a grand total of $70 more than your i7-860 BY ITSELF without so much as a stick of RAM or anything according to Intel. [intel.com]

                So if you want to sit here and argue that you are one of the 1% that actually NEED every MHz of speed you can get, which until we see benches done that are compiled with GCC I wouldn't trust the benches BTW but that is a different story, then fine, do so. But the bang for the buck is so far in AMD's camp right now it isn't even funny, you can choose from several quad cores including fully unlocked for less than a Pentium Dual, and if all you care about is power the AMD Jaguars spank the Intel Atoms on performance while using less than 25w for a quad. AMD is just a crazy deal ATM which is why I've had no complaints when it comes to being AMD exclusive, the customers get great performance at a great price.

                  The problem is though that AMD's single core performance is not just lacking, it is appalling. a quad core i7 will easily outperform a hexacore AMD on multi threaded loads and it will absolutely cream it on single threaded/sequencial loads. AMD has it's advantages, but performance an longevity aint it. If you are trying to save a few dollars and bang for buck is most important than AMD does well. But if you want performance then AMD aren't even playing in the same league.

      Not sure what you're thinking..

      A Linux graphics card driver has 3 components: the kernel module, the X module and the libGL/CL/etc implementation.
      There are two AMD driver for Linux -- the proprietary one and the open source one, each with it's own 3 components.

      The proprietary one offers better OpenGL/OpenCL performance and features (eg, OpenGL 4.4 instead of 3.1), as well as official certification for a number of applications.
      But it also tends to suffer from system integration issues, at the kernel and X level. Sometimes, they work poorly for basic things, they don't work with the latest kernel or X for a while, etc.

      So, what looks here is that AMD wants to reduce the proprietary to the libGL/CL component and leverage on the open source for the kernel driver. Maybe X driver too, eventually.
