A Turkish website known for posting pre-release information is reporting that AMD's Bulldozer launch is being pushed back by a few weeks. The reason, according to Donanimhaber.com, is AMD is having trouble churning out chips capable of reaching the clockspeeds required by revisions B0 and B1, though whether they're referring to the base clockspeed or Turbo Core is unclear.

 

As the story goes, AMD is planning to launch the following Bulldozer models:

 

FX-8150: 3.6GHz (4.2GHz Turbo Core), 8-core, 8MB L2 cache, 125W

FX-8120: 3.1GHz (4GHz Turbo Core), 8-core, 8MB L2 cache, 125W/95W

FX-8100: 2.8GHz (3.7GHz Turbo Core), 8-core, 8MB L2 cache, 95W

FX-6120: Clockspeeds TBD, 6-core, 6MB L2 cache, 95W

FX-6100: 3.3GHz (3.9GHz Turbo Core), 6-core, 6MB L2 cache, 95W

FX-4120: Clockspeeds TBD, 4-core, 6MB L2 cache, 95W

FX-4100: 3.6GHz (3.8GHz Turbo Core), 4-core, 4MB L2 cache, 95W

 

According to Donanimhaber, all seven processors will sport 8MB of L3 cache and support DDR3-1866 memory. All are also being built on a 32nm manufacturing process and are now expected to launch in August and September, depending on SKU.

AMD's next generation of graphics processors (GPUs) that will be branded under the HD 7000 series, are reported to be PCI-Express Generation 3 compliant. The desktop discrete graphics cards will feature PCI-Express 3.0 x16 bus interfaces, and will be fully backwards-compatible with older versions of the bus, including Gen 1 and Gen 2. Motherboards sold today feature Gen 2 PCI-E slots, although some of the very latest motherboards launched by major vendors feature PCI-Express 3.0 slots.

The new bus doubles the bandwidth over PCI-E 2.0, with 1 GB/s of bandwidth per lane, per direction. PCI-Express 3.0 x16 would have 32 GB/s (256 Gbps) of bandwidth at its disposal, 16 GB/s per direction. AMD's next generation of GPUs, codenamed "Southern Islands" will be built on the new 28 nm process at TSMC, and will upscale VLIW4 stream processors. Some of the first PC platforms to fully support PCI-Express 3.0 will be Intel's Sandy Bridge-E. Whether AMD's GPUs have hit a bandwidth bottleneck with PCI-E Gen 2, or is AMD trying to just be standards-compliant, is a different question altogether.

Sandy Bridge-E Model Numbers, Clock Speeds Surface

Here are details of the first three models of Intel's "Sandy Bridge-E" Core i7 processors in the LGA2011 package. Some of these details were made public as early as mid-April. It was then analyzed that Intel was driving two distinct lines of LGA2011 client processors: Enthusiast and Performance, and within Performance, there were BClk multiplier-unlocked six-core, and locked quad-core chips. With the new series, Intel will move to the 3000 series of processor model numbering, indicating that the new processors will be part of Intel's 3rd generation Core processors, even though they're based on the Sandy Bridge architecture.

Before we move to the model numbers, here's a quick run up of the brand extenders. "X" denotes Extreme Edition, "K" denotes "Unlocked" (BClk multipler unlocked). Leading the pack will be Core i7-3960X Extreme Edition. This six-core (6 cores, 12 threads with HTT) chip has a nominal clock speed of 3.30 GHz, Turbo Boost speed of up to 3.90 GHz, and features the full 15 MB of L3 cache present on the Sandy Bridge-E silicon. Expect this chip to have a four figure price-tag.

Next up, is the Core i7-3930K, with 6 cores, 12 threads, a nominal clock speed of 3.20 GHz, and Turbo Boost speed of 3.80 GHz; but 12 MB of L3 cache compared to 15 MB on the Extreme Edition chip. This chip features an unlocked BClk multiplier, making overclocking it possible.

The most affordable LGA2011 chip will be Core i7-3820, with 4 cores, 8 threads, nominal clock speed of 3.60 GHz, Turbo speed of 3.90 GHz, and just 10 MB of L3 cache. Unlike the other two, this one has its BClk multiplier locked. All three models feature quad-channel DDR3 memory controllers, but it is likely that the lower-end models could also have lower DRAM multiplier limits. All three chips will have other features in common, including a PCI-Express 3.0 root complex that gives out two x16 links to drive graphics.
