AMD Zambezi to Use AM3+ Platforms
Advanced Micro Devices said that its next-generation desktop processors code-named Zambezi will use socket AM3+ platforms, which will be backwards compatible with the firm's existing AM3 products. While the latter is an advantage for the platform, it may be a disadvantage for eight-core processors based on Bulldozer micro-architecture.

"The existing G34 and C32 server infrastructure will support the new Bulldozer-based server products. In order for AMD’s desktop offering to fully leverage the capabilities of Bulldozer, an enhanced AM3+ socket will be introduced that supports Bulldozer and is backward-compatible with our existing AM3 CPU offerings," an official from AMD said in an interview with Planet3DNow web-site.

Apparently, it was possible for AMD to make Bulldozer microprocessors compatible with existing AM3 infrastructure, but in order to do that, the company would have to sacrifice certain important features of the new core.

"When we initially set out on the path to Bulldozer we were hoping for AM3 compatibility, but further along the process we realized that we had a choice to make based on some of the features that we wanted to bring with Bulldozer. We could either provide AM3 support and lose some of the capabilities of the new Bulldozer architecture or, we could choose the AM3+ socket which would allow the Bulldozer-base Zambezi to have greater performance and capability," the official said.

The compatibility with older microprocessors allows AMD to simplify transition to the new micro-architecture and process design since the new AM3+ platform will support inexpensive chips from day one. However, such compatibility also means that AMD Zambezi processors will only support dual-channel memory controller. Considering the fact that all modern high-end Intel Core i7 processors with up to six cores feature triple-channel memory controller, it is unclear how AMD plans to "feed" eight cores of Zambezi with dul-channel DDR3 without creating bottlenecks.

AMD Bulldozer-based processor code-named Zambezi will have up to eight cores along with a new TurboCore dynamic acceleration technology. Thanks to the new micro-architecture the chip promises to be faster than existing AMD products.

Yup, they are going to AM3+, but AM3+ mobo still can support AM3 processors.

AMDs Eight-Core Bulldozer Processors to Get Massive Cache
The eight-core microprocessors from Advanced Micro Devices based on the Bulldozer micro-architecture that feature Orochi design will get massive internal cache systems compared to current-generation of chips. In total, the top-of-the-range single-die processor will have 16MB of cache.

AMD Orochi chip (which is a universal server and client design that will power Valencia, Zambezi and possibly other implementations of first-gen Bulldozer family) will have 8MB unified level-three cache, according to a document seen by X-bit labs. Since eight-core Orochi features four dual-core Bulldozer modules, each of which is believed to have 2MB of shared level-two cache, the whole chip will pack in whopping 16MB of SRAM, a 77% increase from the current six-core microprocessors that have 9MB of cache in total.

Large L2 caches will help AMDs next-generation microprocessors to ensure higher performance in single-threaded applications compared to todays multi-core chips that only have 512KB of L2, whereas massive L3 cache will maximize memory bandwidth. In both cases this will bring notable performance gains compared to todays Stars/Greyhound architecture.

AMD Orochi design is the companys next-generation processor for high-end desktop and server markets. The chip will feature eight processing engines, but since it is based on Bulldozer micro-architecture, those cores will be packed into four modules. Every module which will have two independent integer cores (that will share fetch, decode and L2 functionality) with dedicated schedulers, one floating point unit with two 128-bit FMAC pipes with one FP scheduler. The chip will have shared L3 cache, new dual-channel DDR3 memory controller and will use HyperTransport 3.1 bus. The Orochi chips will use new AM3+ form-factor and will require brand new platforms.

The Six Differences Between AM3 and AM3+ Socket.
AM3+ socket :
user posted image
user posted image
AM3+ pin socket is larger than AM3 pin socket by 11%, so the performance of electricity also different.
To prevent breaking the pin on the CPU when putting it on AM3 motherboard, you must be careful.
user posted image
The difference is not only limited on appearance only, but also technical specification.
AM3+ socket has faster link between CPU and power supply controller.
It uses the design on 3.4MHz VID. It enables better power management and power saving.
For your information, AM3 motherboard only provide 400KHz, which is obviously slower.
user posted image
AM3+ motherboard also can reduce the ripple by 22%, making the power management more scientific, better stability.
user posted image
Because of the advance architecture and high core number of Bulldozer, motherboard is required to provide more electricity.
So, AM3+ socket can provide more 32% of electricity than AM3, to meet the requirement of Bulldozer.
user posted image
In addition, AM3+ motherboard got adjusted cooler bracket.
According to there said, it can reduce the temperature of CPU at certain degree.

Recently, we already saw the engineering sample of Llano APU from AMD.
Let's understand it.
user posted image
Because of Llano APU uses socket FM1 (which is not like E-350, soldered with motherboard), it is same with current desktop processor, able to be assembled to and disassembled from the motherboard.
The following motherboard is with socket FM1.
user posted image
Because of this motherboard is used for testing, so you can see a lot of custom soldering.
There are a lot of testing point on the motherboard too, mainly is for the engineers to test the status of the system.
This testing motherboard is powered by FCH A75 chipset. This chipset provides native USB 3.0 support, and does not need third party chip to support that.
It provides a front USB 3.0 connector, 4 DDR3 slots and 5 SATA ports. For power, this motherboard uses 3+2 phase power design. Due to APU got a good GPU integrated, we predict the actual product will provide even better.

In the expansion side, it provides 1 PCI-E x16 slot, 2 PCI-E x4 slots, 1 PCI slot and 1 Mini PCI-E slot. For I/O interface, the motherboard provides HDMI, DisplayPort and D-Sub. Due to the picture is not clear, so we guess it also has a gigabit ethernet LAN, 4 USB 2.0, 6 channel audio card and 1 E-SATA socket.

AMD A-Series desktop APU will have 4 K10.5+(or known as Husky) x86 cores, Radeon HD6000 class "BeaverCreek" GPU(either 300 or 400 stream processors).
For 2 cores variants, it will have "WinterPark" GPU (160 stream processors).
The related products will support dual channel DDR3, with highest 4MB cache support. Part of the products will support Turbo Core (Dynamic clock boosting), and special multi-GPU support. The first batch of A-series APU will be available at 2011 Q3, including 2 cores and 4 cores. The TDU of them is 100W/65W(Quad Core) and 65W. In 2011 Q4, AMD will renew the processors, making brand news A8, A6 and A4 series APUs.

AMD and it's partners give high expectation to the graphic performance of APU, as the integrated GPU has 400 stream processors, will far faster than the GPU in Sandy Bridge processors, attracting the multimedia gamers. And also, AMD pointed out, the calculating ability and usage of HD6000 series GPU will increase the performance of non-gaming performance greatly.

Intel is the leader when it comes to smaller manufacturing process in the semiconductor industry. However this trend cannot continue for long as the limit for silicon is near, I won't mention numbers here even though I know because the future is still unknown but we will not be going beyond or near 1nm I can guarantee that. They have to find some other ways to improve other than reduce the manufacturing node.

If BD is released and it doesn't show a strong single threaded performance against SB then it is within my assumption as well because BD is a server based CPU and will be stronger in terms of multithreaded applications. AMD aims to reclaim the server market with BD so I am not surprised at all. But of course I hope there would be some kind of silicon fairy dust they can throw in that makes it an all rounder champion.  tongue.gif

The images, which were published by Zol.com.cn web-site, also point to new model numbers for the chips: FX-8150, FX-8100, FX-6100 and FX-4100, which may indicate that the company intends to alter previously set specifications of the chips.

Hope AMD will not let me to give them :

Another leaked benchmark result.
FX-8110P+GTX560 Ti, got 26676 marks.
For comparison, i7 2600K+GTX580 got 29152 marks.
And also, physics acceleration didn't being turned off the both benchmarks.
From the result, the CPU mark is 81917, much higher than i7 2600K (64164).
user posted image
This screenshot is actually came from the Gigabyte Product Certificating Engineer, Alain Sam-Lai.
The CPU-Z used is internal testing version, 1.58.1. This version is mainly to add support for identifying Bulldozer.
The actual changelog is :
- Added support for FMA4, XOP on Bulldozer processors.
- Added support for AMD Zambezi, Valencia, Interlagos and other processors with Bulldozer architecture.
- Added support for AMD 990FX+SB950 chipset.
- Added support for AM3+ socket.
- Added support for AMD Turbo Core.
- Added new AMD logo, including AMD FX-series.
- Support DDR4 1.2v standard briefly.
- Added i7 2650/2700/2800K processor's ID. (brows.gif)
- Fixed some bugs.

Actually the first Bulldozer benchmark result leaks are 3DMark06, Cinebench R10 and SuperPi. Maybe the processor was engineering sample, so the result is not satisfying. The later lated SuperPi result shows, the single core performance of Bulldozer is very strong. Result of 1 million Super Pi is 7.800s, much higher than i7 2600K's 10.047s. For multithreaded performance, Bulldozer got 166.895 in WPrime 1024M, nearly 50% faster than i7-2600K's 246.34s.

Looks like the performance of this generation of Bulldozer processor is hopeful, but the launching date is still unknown. Previous news was stating Bulldozer will be launched in June. But latest news showed Bulldozer will be delayed to July. The upgraded version of Bulldozer will be launched in September. These shows, the first generation of Bulldozer can be assured to be launched in July, as the 2 months interval for releasing new models are normal.

Yet another 1. (Source : http://www.chiphell.com/forum-80-1.html)
Computex 2011 is finally launched.

About the Bulldozer performance, before the launching, there are a lot's of rumors already, but the trust level is not high.
Especially about the performance, just take them as joke.

Originally, AMD planned to launch Zambezi processors on Computex 2011, but the performance of B0 and B1 didn't reach the expected level.
The B2 revision is under manufacturing.

AMD unofficially says Bulldozer is planned to launch in Q3, but looks like now, most probably the launching will be at end of July.
But, first of all, the B2 revision must satisfying, but the actual performance is still unpredictable.

Interesting article.

Updated news for the delay of Bulldozer.
QUOTE
FX series processor are already working correctly, does not have any problem. But the performance is not satisfying. The B0 and B1 revision only can reach 2.5GHz stock, 3.5GHz turbo boost maximum. It is not yet to reach the AMD's expectation level, and unable to compete with opponent. So, AMD is adjusting the design, going to B2 revision. Hopefully the TDP is maintained while increasing the clock. But obviously, this requires quite amount of time.

AMD will have to sell Bulldozer eventually so September is not that far. It's better that AMD delays a few months to work out the problems rather than having to recall their CPU or having many unsatisfied customers by selling a inferior product. By the time AMD releases their CPU with the latest stepping their 32nm should mature a bit more.

Rather than repeating the history of Intel. whistling.gif
