Some are specific to Intel only, some to AMD. Supported virtual machine optimization technologies. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters. Phenom will also be the first monolithic quad-core x86 processor to hit the market, which does have some technical advantages but we're not sold on whether or not we'll see any tangible real. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Useful when planning a future computer configuration or upgrading an existing one. Information on Phenom X4 9600 compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. These parameters can generally indicate CPU performance, but to be more precise you have to review its test results. This list was acquired from an actual AMD Phenom X4 9950 processor with the help of the x86 CPUID instruction. The latency improvement is dependent on cache frequency however, and this has been dropped from 2.0GHz on the 98 Phenom X4s to 1.8GHz in both Phenom IIs.Basic microprocessor parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state. CPU ID information for the Phenom X4 9950 (125W) Detailed characteristics of processor's internals, including x86 instruction set extensions and individual instructions, high- and low-level technologies, are listed below. In conjunction with this, there has been a 50 percent increase in cache associativity from 32 to 48-way and also a two-cycle latency improvement. The first graph shows the relative performance of the CPU compared to the 10 other common (single) CPUs in terms of PassMark CPU Mark. This is made using thousands of PerformanceTest benchmark results and is updated daily. To aid this, there's also a "Coherent DRAM Prefetch" function that allows the memory controller to generate probes for DRAM prefetch requests too.īigger CacheIn terms of cache, the L1 and L2 cache sizes remain the same as the original Agena-based Phenom chips, but the 元 cache size has increased from 2MB to 6MB on the 45nm Phenom II. Price and performance details for the AMD Phenom 9550 Quad-Core can be found below. The DDR2 memory controller on the Phenom II CPUs has been upgraded though to including an adaptive prefetch scheme which adjusts the prefretching depth depending on the buffer space available, effectively better making use of available resources by allowing for more chances to have the data needed ready to use locally. These CPUs are AM2+ meaning DDR2 only, however AM3 arrives in February and supports both DDR2 and DDR3. In contrast, AMD's SOI technology stems on from its 65nm SOI process. Get the competitive edge for AI, data center, business computing solutions & gaming with AMD processors, graphics, FPGAs, Adaptive SOCs, & software. Buy Open Box: AMD Phenom 9550 - Phenom X4 Agena Quad-Core 2.2 GHz Socket AM2+ 95W Processor - HD9550WCJ4BGH with fast shipping and top-rated customer service. The 45nm SOI fabrication process is slightly different to Intel's High-k Metal Gate which uses newer, alternative materials and was the biggest change in transistor technology since the 60s. AMD Phenom X4 Agena Processors List AMD Phenom X4 9850B Phenom X4 (Agena), 4 / 4, 2.5 GHz, AMD Socket AM2+, 2MB (shared) AMD Phenom X4 9750B Phenom X4 (Agena). Processor is designed for desktop computers. This time around though, AMD claims its 45nm CPUs have a much greater performance overhead. AMD Phenom II X4 B45 - 4-core processor with a clock frequency of 3100 MHz and 2rd level cache 2048 KB. The latter, in particular, was AMD's single biggest problem with the 65nm Phenoms - the other "issue" was the limited overclocking and that caused enthusiasts to shy away and invest in Intel instead. The company's 45nm silicon on insulator (SOI) process allows for cooler CPUs, which affords AMD more thermal overhead for larger caches and higher clock speeds. Phenom II X4 920 UK Price (as reviewed): TBAĪMD's 45nm CPUs have arrived and while some might claim "better late than never" seeing as Intel has been shipping its own for more than a year now, the rest of us might be pleased they have arrived at all, given the recent struggles inside the company. Phenom II X4 940 UK Price (as reviewed): TBA AMD's Phenom II X4 940 and 920 Manufacturer AMD
