SiFive, Inc., the founder and leader of RISC-V computing, today announced the company will support Intel Foundry Services (IFS) innovation fund's goal to build innovative new RISC-V computing platforms optimized for Intel process technology. The $1B Intel fund will support the creation of disruptive technologies to address modern computing challenges, with the Intel-SiFive collaboration aiming to extend the RISC-V ecosystem. Compute blocks in future silicon chips, optimized for specific classes of workloads, require a vibrant market of semiconductor IP that is further enabled by SiFive's leading RISC-V processor IP optimized and available to customers of IFS. The open nature of the RISC-V instruction set architecture creates freedom to innovate, with specifications and extensions developed by expert contributors from leaders in the semiconductor industry, research institutions, and academia.

SiFive has partnered with IFS to develop a RISC-V development platform, codenamed "Horse Creek," featuring a multi-core SiFive Performance P550 processor, and implemented on the Intel 4 technology platform, on track for availability in 2022. The "Horse Creek" SoC will enable a new generation of RISC-V developer boards, continuing the tradition of SiFive HiFive boards that have helped drive the growth of the RISC-V ecosystem.

AMD has implemented price-cuts for its desktop CPUs under the Athlon X2, Phenom and Phenom II series. The price cuts affect Athlon X2 model 7750, Phenom X3 models 8750, 8650 and 8450, and the company's current flagship product Phenom II X4 940. The Phenom X3 8750 in particular, is pushed into the $100 mark with its 26% reduction in price.

With the revised price-table, AMD looks to make space for three upcoming products that include the much awaited Phenom II X4 955 Black Edition. Expected to have reached retail in the US on April 20, the chip has been pushed to a later date, when the company plans four launches in all: Phenom II X4 955, Phenom II X4 945, Athlon X2 7850, and AMD Overdrive 3 software.

Phenom II X4 945 is a 3.0 GHz quad-core processor with its multiplier locked at 16x, while the Athlon X2 7850 takes over as the company's flagship dual-core chip spec'd at 2.80 GHz, 3 MB of total cache, and a TDP of 95W. The chip is based on the 65 nm Kuma core. Phenom II X4 955 has already received listings in Europe, where it is priced at €229.90 including taxes.

AMD is releasing a trio of dual-core desktop processors based on the K10 architecture, under the Athlon X2 7000 series. The trio consists of the overclocker-friendly 7750 Black Edition clocked at 2.70 GHz, the 7550 at 2.50 GHz and the 7450 at 2.40 GHz. The core, codenamed "Kuma" sports a basic cache design similar to the Phenom X3 and Phenom X4 processors, with 512 KB of L2 caches per core, and a shared L3 cache of 2 MB. The updated memory controller provides native support to the PC2-8500 (DDR2 1066 MHz) memory standard. The processor now sports a HyperTransport 3.0 3600 MT/s system interface. These, apart from the other tweaks AMD introduced with the K10 architecture give it an edge over current K8 based dual core AMD chips. The core is manufactured in the 65nm node.

AMD lifted the NDA over the Athlon X2 7000 series, following which several website posted reviews on the processors. Most of these reviews covered the Athlon X2 7750 Black Edition. The chip clocked at 2.7 GHz was found to be around 15% faster than a previous-generation Brisbane chip running at the same frequency, according to X-bit Labs, whose evaluation included several synthetic and real-world benchmarks. The same review team was able to overclock the chip to 3.30 GHz (+22 %) aided by a Zalman 9700 air cooler. The Athlon X2 7750 Black Edition will be priced at US $79. Links to some of the reviews are provided below.

AMD is releasing its dual-core desktop processor based on the 65nm K10 architecture, codenamed Kuma. One of the first SKUs based on the core, the Athlon X2 7750, has been evaluated by Donanim Haber. The Athlon X2 7750 comes with a clock-speed of 2.70 GHz, and a HyperTransport 3.0 system interface. It has 512 KB of L2 cache per core, and a shared L3 cache of 2 MB. Donanim Haber put this chip to test on a Foxconn A7DA-S (AMD 790 GX + SB750) motherboard, with 2 GB of 800 MHz DDR2 memory. It was compared to the Intel Core 2 Duo E8200, Core 2 Duo E8400, Core 2 Duo E6420, AMD Phenom X3 8750 and Athlon X2 5200+ (Brisbane), all running at stock speeds.

Industry informer DigiTimes shared today some information on the upcoming Deneb processor family from AMD. According to their information, AMD is planning to launch six high-end 45nm quad-core CPUs (Deneb) and four entry-level (Propus) including 20x00, 18x00, 16x00 and 1xx00e models, in the first quarter of next year. Two of these processors will be available earlier in November of this year - the 3GHz Phenom X4 20550 and 2.8GHz 20350 for socket AM2+ systems.
AMD will also launch six 45nm triple-core CPUs (Heka and Regor) including 14x00, 12x00 and 1xx00e series. These triple-core CPUs will enter design validation test (DVT) and start shipping in the first quarter next year.
In the second and third quarter of next year AMD will also start shipping its 45nm AM3-based dual-core CPUs, part of the Regor family.
Although the chipmaker will largely enter the 45nm generation, in order to prevent potential yield rate problems from the new process, it will launch seven 65nm CPUs including three quad-core Phenom X4 CPUs (Agena) - 9950 (120W), 9850 (95W) and 9450e (65W), and two Athlon X2 CPUs (Kuma) - 7750 and 7550 in the first quarter of 2009, while two low-power Athlon X2 CPUs (Brisbane) - 5050e and 3250e, will launch in the near future.
Launching of the new Phenom processors will also lead to new price reductions and last order notices for some of the older processors. Unfortunately, there is no additional information.

Industry sources reveal that AMD would be branding its Kuma dual-core processor as Athlon X2 7000 series. These processors are aimed to compete with Intel's Core 2 Duo E7000 series processors. Kuma continues to use the 65nm SOI fabrication process. The core sports 512 KB L2 cache per core, and a shared 2 MB L3 cache. Surprisingly, despite having sub-3.00 GHz clock speeds, the processors have rated TDP of 95W.

These processors use a broader 3600 MT/s HyperTransport interface, and feature DDR2 memory controllers that support the PC2-8500 (1066 MHz) standard. As for the models, the Athlon X2 7550 has a clock speed of 2.50 GHz, and an FSB multiplier of 12.5x. The Athlon X2 7750 comes with the clock speed of 2.70 GHz, and a FSB multiplier of 13.5x. Both processors are expected to be out by Q1 2009.

Time draws closer for the Athlon 64 X2 to retire. It has seen its good and bad days, leading Intel versus the Pentium D and trailing it versus the Core 2 Duo. German site Hardware Infos shed light on the primary lineup of the dual-core edition based on the K10 architecture, the Phenom X2. There are no core architectural changes for the Phenom X2, codenamed "Kuma" over the K8, except that like the Phenom X3 and X4, these chips feature 2 MB of L3 cache apart from 512 KB caches per core and the revised HyperTransport interface. The listed models come at a rated TDP of 45W. The first three Kuma chips listed have clock-speeds ranging from 1.90 GHz to 2.30 GHz and have been given model numbers that look confusing to the older PRN system AMD employed, with the top Athlon 64 X2 rated at 6400+. The later releases of the older X2 using the Brisbane core broke away from the older PRN and we saw models such as 4450e, 4850e or 4850b (note the absence of the "+").

The naming of these chips asserts that. For example, the 1.90 GHz Kuma part is named Phenom X2 GE-6400. Going by the performance evaluations of other parts based on the K10 architecture, at 1.90 GHz + the 2 MB L3 cache, this part might not be on par with the Windsor core Athlon 64 X2 6400+. Contradicting earlier reports that AMD would work out Kuma parts on the 45 nm fabrication process, all three Kuma parts reported are based on the 65 nm fab process.
