The AMD Closed Loop System
Closed loop water cooling is not new, but it certainly is a pretty hot topic now. Some of the first units out there had some interesting issues (like internal corrosion clogging everything up), but once those teething problems were solved the closed loop systems turned out to be pretty effective and easy to install. Initially these units had the performance of a top end air cooler, but with a lot lower noise. The latest generation of liquid cooling systems (LCS) is now further improved and provides performance approaching that of larger, more complex cooling systems. These products will not replace exotic systems like phase change, but they provide a lot of cooling in a fairly decent sized package.
Clean lines and graphics give this box a striking look without being tacky.
Last year with the introduction of the AMD FX-8150, AMD decided to create a SKU which not only included the CPU, but also a fairly robust LCS. This unit is based on an Asetek design which features a double wide cooler/reservoir with the push-me/pull-ya fan combination. Other manufacturers offer this particular product under a variety of names, but this is simply an AMD FX branded unit with some small cosmetic changes to differentiate it from other units.
AMD will eventually offer this cooler with the new Vishera based FX-8350 CPU (or at least we assume they will), and we wanted to take this combination out for a spin. In our FX-8350 review we did not hit the overclocking targets that AMD had set. In most literature that we were provided AMD stated that most FX-8350 parts would be able to hit around 5 GHz with some aggressive cooling. In our review I was able to get to around 4.6 GHz max and around 4.5 GHz stable with better than average cooling. The results were not as impressive as we had hoped, but we again did not have a top end cooling solution such as what AMD provides with this particular LCS.
With a brand new LCS in hand, I retested the FX-8350 to see how hard it could be pushed. I also wanted to see how this particular unit performance in terms of thermal properties. The results were quite surprising for me, as this is my first real experience with a LCS.

The GPU is slowly becoming the parallel processing complement to your branching logic-adept CPU. Developers have been slow to adopt this new technology but that does not hinder the hardware manufacturers from putting on a kettle of tea for when guests arrive.
While the transition to GPGPU is slower than I am sure many would like, developers are rarely quick on the uptake of new technologies. The Xbox 360 was one of the first platforms where unified shaders became mandatory and early developers avoided them by offloading vertex code to the CPU. On that note: how much software still gets released without multicore support?
Phoronix, practically the arbiter of all Linux news, decided to put several GPU drivers and their manufacturers to the test. AMD was up first and their results showed a pretty sizeable jump in performance at around October of this year through most of their tests. The article on NVIDIA arrived two days later and saw performance trended basically nowhere since February with the 295.20 release.
A key piece of information is that both benchmarks were performed with last generation GPUs: the GTX 460 on the NVIDIA side, with the 6950 holding AMD’s flag. You might note that 295.20 was the last tested driver to be released prior to the launch of Kepler.
These results seem to suggest that upon the launch of Kepler, NVIDIA did practically zero optimizations to their older "Fermi" architecture at least as far as these Linux OpenCL benchmarks are concerned. On the AMD side, it seems as though they are more willing to go back and advance the performance of their prior generation as they release new driver versions.
There are very few instances where AMD beats out NVIDIA in terms of driver support -- it is often a selling point for the jolly green giant -- but this appears to be a definite win for AMD.

AMD appears to be jumping the gun a bit here but has decided to announce the Radeon 8000M-series of mobile GPUs prior to CES. Before you get all riled up about the next generation of graphics technology, you should know that the new parts we are showing here are still built on the same 28nm Graphics Core Now (GCN) architecture that you'll find in the Radeon HD 7000 series of desktop graphics cards and even some already-existing Radeon mobility parts like the HD 7970M. We were told there are "some changes" but details were minimal.
Radeon HD 8500M and 8600M GPUs will both feature 384 stream processors with the variance related to the maximum clock speed. The 8600M will hit 775 MHz core clock while the 8500M will cap out at 650 MHz. Memory speeds are identical. Keep in mind that the desktop Radeon HD 7750 card has 512 stream processors and it runs at up to 900 MHz so you that can put the performance of these mainstream GPUs in perspective.
The 8700M uses the same 384 stream processor GPU though it gets a bit higher clock speed at 850 MHz. The 8800M is the only GPU announced today to increase the core count to 640 stream processors and a clock speed of 700 MHz for a total compute capability of 992 GFLOPs. Though the specifications are nearly equivalent to the build of the desktop Radeon HD 7770 part it is worth mentioning that the theoretical peak performance of that GPU is 1.28 TFLOPs; nearly 30% higher than the 8800M.
AMD was coy but hinted that this mainstream product announcement will be added to later in Q1 with higher end enthusiast-level SKUs. No 8900s yet guys, check back later.
When asked about the changes in this mobility GPU release compared to the 7000M series already available today, we only know that this is built on the same 28nm process but that the "architecture is slightly different and more efficient" than the 7000 chips. These are NEW chips and are NOT rebrands of currently available products. We don't have die sizes, transistor counts or TDPs until further notice.
AMD did provide a couple of quick graphs comparing the performance of the Radeon HD 8870M against the GeForce 650M G5 and The 8770M against its own previously releaesd 7670M part. Take all of this with a grain of salt until we can do our own testing, as per usual.
For now, I would say our readers should be very timid about the idea of a new series of GPUs from AMD without more information on the actual changes in performance will be compared to Souther Islands. Based on what we are hearing the changes are very minor.

Okay, so this has been an interesting debate. After the first rumors and reports that Intel might be killing the DIY PC (or at least crippling it) by removing the socketed option for future processors after the Broadwell architecture, the Internet had a hissy-fit. Josh debated here that the future didn't look at that bleak at all and AMD chimed in later with its commitment to sockets into 2014 and beyond.
It looks like Intel has officially addressed the issue through a story at MaximumPC.com:
Intel remains committed to the growing desktop enthusiast and channel markets, and will continue to offer socketed parts in the LGA package for the foreseeable future for our customers and the Enthusiast DIY market. However, Intel cannot comment on specific long-term product roadmap plans at this time, but will disclose more details later per our normal communication process.
While those in the community that see the glass half empty will look at Intel's use of "foreseeable future" as a red herring, we have to at least attempt to take Intel at its word until any more details might be released to counter it.
Let the debate continue!

Over the past week or more we have been seeing a lot of news about Intel's rumored move to leave the world of socket-based processors behind after the pending Broadwell parts are released as BGA - ball grid array - and are soldered to motherboards directly. I would highly encourage everyone to read Josh's thoughts on the subject that are not nearly as damning as others might have you believe.
However, we got this official note from AMD earlier in the week that I thought I would share:
AMD has a long history of supporting the DIY and enthusiast desktop market with socketed CPUs & APUs that are compatible with a wide range of motherboard products from our partners. That will continue through 2013 and 2014 with the “Kaveri” APU and FX CPU lines. We have no plans at this time to move to BGA only packaging and look forward to continuing to support this critical segment of the market.
As the company that introduced new types of BGA packages in ultrathin platforms several years ago, and today offers BGA-packaged processors for everything from ultrathin notebooks to all-in-one desktops, to embedded applications and tablets, we certainly understand Intel’s enthusiasm for the approach. But for the desktop market, and the enthusiasts with whom AMD has built its brand, we understand what matters to them and how we can continue to bring better value and a better experience.
Obviously AMD is trying to persuade PC builders that not only is its path the safest in the future but maybe that supporting AMD today might help make sure it can arrive to the future well enough to continue the enthusiast path.
If Intel even starts to heavily side with BGA processors, is a move to AMD in your future again? Leave your thoughts in the comments below!

Tagged: servers, opteron 4300, opteron 3300, opteron, amd
AMD has officially released a number of new server processors based on its latest Piledriver cores. The new Opteron 4300 and Opteron 3300 series processors will replace the 4200 and 3200 series, and are aimed at the server market. The 4300 series uses Socket C32 while the Opteron 3300 processors use socket AM3+. They are significantly cheaper Piledriver-based parts than the higher-end Opteron 6300 series processors. AMD is aiming these lower cost Opterons at servers hosting websites and internal applications for small to medium businesses.
There are a total of nine new Opteron processors, with three being 3300 series an six being 4300 series. Both the 3300 and 4300 series Opterons are socket compatible with the previous generation 3200 and 4200 series respectively, allowing for an upgrade path in existing servers. According to AMD, the new Piledriver-based processors have 24% higher performance per watt and use 15% less power than the previous generation parts based on the SPECpower and SPECint benchmarks. AMD is also touting support for low power 1.25V memory with the new chips.
The chart below details the specifications and pricing all of the new Opteron parts.
The new AMD Opteron 3300 series includes two quad core and one eight core processor. The parts range from 1.9GHz to 2.6GHz base and have TDPs from 25W to 65W for the lowest and top end parts respectively. AMD-P, AMD-V, and AMD Turbo Core technologies are also supported. As far as memory goes, the 3300 series supports up to four DIMMs and 32GB per CPU. Further, a single x16 HyperTransport 3.0 link rated at 5.2GT/s is included.
Moving up to the 4300 series comes with an increase in price but you also get more cores, more memory, and faster clockspeeds. The Opteron 4300 series has one quad core 4310 EE, three six core CPUs, and two eight core parts. Base clocks range from 2.2GHz to 3.1GHz while boost clocks start at 3.0GHz and go to 3.8GHz. On the low end, the Opteron 4310 EE has a 35W TDP and the top-end 4386 has a 95W TDP. The 4300 series supports dual channel DDR3 1866 memory with up to six DIMMs and 192GB per CPU. Moving up from the 3300 series also gets you two x16 HyperTransport 3.0 links at 6.4 GT/s.
The new server processors are available now with prices ranging from $174 to $501. In addition, pre-built server options from Supermicro and Seamicro (SM15000) are currently available, with options from Dell and a number of other companies on the way. The prices seem decent, and these chips could make the base for a nice 2P server that brings you Piledriver improvements for much less than the relatively expensive 6300 series processors that we covered previously.
