The Tech Report managed to get some more information out of AMD about the new FX-9000 series that the net has been buzzing about. We now have confirmation that the base clocks for the FX-9590 and FX-9370 are 4.7GHz and 4.4GHz. They also confirmed that 220W TFP is relatively accurate which will make these the hottest chips on the market. While you won't see these chips officially for sale outside of specially built systems, there is a chance a few might pop up on eBay and if you are curious how they might perform there is a link in The Tech Report's article to an overclocked Vishera which will give you a rough idea.
"On Tuesday, AMD introduced its new FX-9000-series processors. The company quoted their peak Turbo speeds (5GHz for the FX-9590, 4.7GHz for the FX-9370) and a rough time frame for availability ("this summer"), but it revealed little else. We were left wondering about base clocks, power envelopes, and potential retail availability."

We have all heard the rumors, but it appears to be true. We had originally heard about a “Centurion” product which would be for extreme overclockers on the AMD side, running at 5 GHz with a 220 watt TDP. Now we finally get to see what all the fuss is about. AMD is releasing two new Vishera based processors that, for the time being, will be limited to system integrators and will be available later this summer.
The top end product is the FX-9590 which has a top turbo speed of 5 GHz. This will be a full four module implementation with the 8 MB of L3 cache. AMD did not give any other details for this particular part. We do not know what the base clock is, we do not know what the TDP is, and we can only assume that the northbridge/L3 cache will be clocked at the standard 2.2 GHz that we have seen on previous Vishera parts.
The second product is the FX-9370 which is again a four module part that has a top turbo speed of 4.7 GHz. Remember that the four modules each have two “cores”, so it is still considered an eight core part. These processors are unlocked, so they can be further overclocked if one so desires. TDP and other details were again skipped for this particular part.
These parts will be going to system integrators first, and I am not entirely sure that AMD will sell them on the market direct to consumers. If AMD does in fact sell to consumers (not implied at all in the press release) then they likely will have to bundle it with a very robust cooler. Probably something along the lines of what we saw with the original FX-8150 LCS bundle.
Consider that the FX-8350 is a 4 GHz base clock product with a max turbo of 4.2 GHz and having a TDP of 125 watts, we probably have to assume that the 220 watt number bandied about is accurate. A pretty beefy air cooler would be required, or the aforementioned liquid cooling system. AMD also likely had GLOBALFOUNDRIES change the “mix” when fabricating these parts. These batches probably feature more leaky transistors that can achieve higher speeds without an extreme amount of voltage.
This is an interesting move by AMD. Remember those TWKR chips that they released that were designed for LN2 use? There were a very limited number of those units, and we can imagine that while the FX-9000 series will be in greater numbers they still will not be commonplace on the retail market. SI’s like Maingear will be introducing systems this summer featuring these chips. Performance will be good with these solutions, but the tradeoff is of course power consumption and heat production as compared to similarly performing (and stock clocked) Intel i7 3770K and 4770K parts.
AMD is doing their best to address the enthusiast market, but until Kaveri hits the streets we will not see any major upgrades beyond these parts.
We received some further info about this chip. The TDP is up in the 220 watt region. It utilizes Turbo Core 3.0 to help achieve those speeds, so it seems that some of the work that went into Richland has made it into these latest FX processors. BIOS updates are probably a must. These chips will only be going to system integrators (SIs) and will be bundled with a liquid cooling system. We have no idea what the price will be since these will only be sold to SIs. Systems should be available after July 16.

Richland is here, in the form of the A10-6800K with a 4.1GHz base clock and 4.4GHz Turbo clock, support for DDR3-2133 and an improved GPU called the 8670D with 384 shaders and a 844MHz clock speed ... all for $142! Computationally you can compare it to a Core i3 or a slower Core i5 but graphically this CPU is head and shoulders above the competition as you can see in X-Bit Labs' testing. You really need to keep the price in mind, as it may not provide as much power as a Core-i5 it costs about half as much which can mean a lot to someone on a tight budget, especially when they can skip purchasing a discrete GPU altogether.
Make sure to check out Josh's reivew where he contrasts the last few generations of AMD chips.
"AMD decided to refresh their Socket FM2 platform and release a new generation of hybrid processors for it based on Richland design. This is exactly the one that earned the “Elite Performance APU Platform” title in the mobile segment."

Trinity... but Better!
Richland. We have been hearing this name for a solid nine months. Originally Richland was going to be a low end Trinity model that was budget oriented (or at least that was the context we heard it in). Turns out Richland is something quite different, though the product group does extend all the way from the budget products up to mainstream prices. We have seen both AMD and Intel make speed bin updates throughout the years with their products, but that seems like it is becoming a thing of the past. Instead, AMD is refreshing their Trinity product in a pretty significant matter. It is not simply a matter of binning these chips up a notch.
Trinity was released last Fall and it was a solid product in terms of overall performance and capabilities. It was well worth the price that AMD charged, especially when compared to Intel processors that would often be significantly slower in terms of graphics. The “Piledriver” architecture powers both Trinity and Richland, and it is an improved version of the original “Bulldozer” architecture. Piledriver included some small IPC gains, but the biggest advantage given was in terms of power. It is a much more power efficient architecture that can be clocked higher than the original Bulldozer parts. Trinity turned out to be a power sipping part for both mobile and desktop. In ways, it helped to really keep AMD afloat.
It turns out there were still some surprises in store from Trinity, and they have only been exposed by the latest Richland parts. AMD is hoping to keep in front of Intel in terms of graphics performance and compatibility, even in the face of the latest Haswell parts. While AMD has not ported over GCN to the Trinity/Richland lineup, the VLIW4 unit present in the current parts is still very competitive. What is perhaps more important, the software support for both 3D applications and GPGPU is outstanding.

AMD may have united GPU and CPU into the APU but one hurdle had remained until now, the the non-uniformity of memory access between the two processors. Today we learned about one of the first successful HAS projects called Heterogeneous Uniform Memory Access, aka hUMA, which will appear in the upcoming Kaveri chip family. The use of this new technology will allow the on-die CPU and GPU to access the same memory pool, both physical and virtual and any data passed between the two processors will remain coherent. As The Tech Report mentions in their overview hUMA will not provide as much of a benefit to discrete GPUs, while they will be able to share address space the widely differing clock speeds between GDDR5 and DDR3 prevent unification to the level of an APU.
Make sure to read Josh's take as well so you can keep up with him on the Podcast.
"At the Fusion Developer Summit last June, AMD CTO Mark Papermaster teased Kaveri, AMD's next-generation APU due later this year. Among other things, Papermaster revealed that Kaveri will be based on the Steamroller architecture and that it will be the first AMD APU with fully shared memory.
Last week, AMD shed some more light on Kaveri's uniform memory architecture, which now has a snazzy marketing name: heterogeneous uniform memory access, or hUMA for short."

heterogeneous Uniform Memory Access
Several years back we first heard AMD’s plans on creating a uniform memory architecture which will allow the CPU to share address spaces with the GPU. The promise here is to create a very efficient architecture that will provide excellent performance in a mixed environment of serial and parallel programming loads. When GPU computing came on the scene it was full of great promise. The idea of a heavily parallel processing unit that will accelerate both integer and floating point workloads could be a potential gold mine in wide variety of applications. Alas, the promise of the technology did not meet expectations when we have viewed the results so far. There are many problems with combining serial and parallel workloads between CPUs and GPUs, and a lot of this has to do with very basic programming and the communication of data between two separate memory pools.
CPUs and GPUs do not share common memory pools. Instead of using pointers in programming to tell each individual unit where data is stored in memory, the current implementation of GPU computing requires the CPU to write the contents of that address to the standalone memory pool of the GPU. This is time consuming and wastes cycles. It also increases programming complexity to be able to adjust to such situations. Typically only very advanced programmers with a lot of expertise in this subject could program effective operations to take these limitations into consideration. The lack of unified memory between CPU and GPU has hindered the adoption of the technology for a lot of applications which could potentially use the massively parallel processing capabilities of a GPU.
The idea for GPU compute has been around for a long time (comparatively). I still remember getting very excited about the idea of using a high end video card along with a card like the old GeForce 6600 GT to be a coprocessor which would handle heavy math operations and PhysX. That particular plan never quite came to fruition, but the idea was planted years before the actual introduction of modern DX9/10/11 hardware. It seems as if this step with hUMA could actually provide a great amount of impetus to implement a wide range of applications which can actively utilize the GPU portion of an APU.
AM3+ Last Gasp?
Over the past several years I have reviewed quite a few Asus products. The ones that typically grab my attention are the ROG based units. These are usually the most interesting, over the top, and expensive products in their respective fields. Ryan has reviewed the ROG graphics cards, and they have rarely disappointed. I have typically taken a look at the Crosshair series of boards that support AMD CPUs.
Crosshair usually entails the “best of the best” when it comes to features and power delivery. My first brush with these boards was the Crosshair IV. That particular model was only recently taken out of my primary work machine. It proved itself to be an able performer and lasted for years (even overclocked). The Crosshair IV Extreme featured the Lucid Hydra chip to allow mutli-GPU performance without going to pure SLI or Crossfire. The Crosshair V got rid of Lucid and added official SLI support and it incorporated the Supreme FX II X-Fi audio. All of these boards have some things in common. They are fast, they overclock well, and they are among the most expensive motherboards ever for the AMD platform.
So what is there left to add? The Crosshair V is a very able platform for Bulldozer and Piledriver based parts. AMD is not updating the AM3+ chipsets, so we are left with the same 990FX northbridge and the SB950 southie (both of which are essentially the same as the 890FX/SB850). It should be a simple refresh, right? We had Piledriver released a few months ago and there should be some power and BIOS tweaks that can be implemented and then have a rebranded board. Sounds logical, right? Well, thankfully for us, Asus did not follow that path.
The Asus Crosshair V Formula Z is a fairly radical redesign of the previous generation of products. The amount of extra features, design changes, and power characteristics make it a far different creature than the original Crosshair V. While both share many of the same style features, under the skin this is a very different motherboard. I am rather curious why Asus did not brand this as the “Crosshair VI”. Let’s explore, shall we?

The differences between Richland and Trinity are not earth shattering but there are certainly some refinements implemented by AMD in the A10-5750. One very noticeable one is support for DDR3-1866 as well as better power management for both the CPU and GPU; with new temperature balancing algorithms and measurement the ability to balance the load properly has increased from Trinity. Many AMD users will be more interested in the GPU portion of the die than the CPU, as that is where AMD actually has as lead on Intel and this particular chip contains the HD8650G, with clocks of 720MHz boost and 533MHz base and increase from the previous generation of 35 and 37MHz respectively. You can read more about the other three models that will be released over at The Tech Report.
"AMD has formally introduced the first members of its Richland APU family. We have the goods on the chips and Richland's new power management tech, which combines temperature-based inputs with bottleneck-aware clock boosting."

AMD Exposes Richland
When we first heard about “Richland” last year, there was a little bit of excitement from people. Not many were sure what to expect other than a faster “Trinity” based CPU with a couple extra goodies. Today we finally get to see what Richland is. While interesting, it is not necessarily exciting. While an improvement, it will not take AMD over the top in the mobile market. What it actually brings to the table is better competition and a software suite that could help to convince buyers to choose AMD instead of a competing Intel part.
From a design standpoint, it is nearly identical to the previous Trinity. That being said, a modern processor is not exactly simple. A lot of software optimizations can be applied to these products to increase performance and efficiency. It seems that AMD has done exactly that. We had heard rumors that the graphics portion was in fact changed, but it looks like it has stayed the same. Process improvements have been made, but that is about the extent of actual hardware changes to the design.
The new Richland APUs are branded the A-5000 series of products. The top end is the A10-5750M with HD-8650 integrated graphics. This is still the VLIW-4 based graphics unit seen in the previous Trinity products, but enough changes have been made with software that I can enable Dual Graphics with the new Solar System based GPUs (GCN). The speeds of these products have received a nice boost. As compared to the previous top end A10-4600, the 5750 takes the base speed from 2.3 GHz to 2.5 GHz. Boost goes from 3.2 GHz up to 3.5 GHz. The graphics portion takes the base clock from 496 MHz up to 533 MHz, while turbo mode improves over the 4600 from 685 MHz to 720 MHz. These are not staggering figures, but it all still fits within the 35 watt TDP of the previous product.
One other important improvement is the ability to utilize DDR-3 1866 memory. Throughout the past year we have seen memory densities increase fairly dramatically without impacting power consumption. This goes for speed as well. While we would expect to see lower power DIMMs be used in the thin and light categories, expect to see faster DDR-3 1866 in the larger notebooks that will soon be heading our way.
