The AMD Athlon 64 FX-57 (Rev-3) is based upon AMD's San Diego core using the Socket 939 ZIF interface. In many respects, the San Diego core is similar to the Venice core AMD previously announced with the release of the 4000+ and FX-55 CPUs. The FX-57 has 128KB of L1 cache (64KB Data and a 64KB Instruction Cache. Based upon the San Diego chip, the FX-57 is the fastest shipping AMD CPU clocked at 2.8GHz. The FX-57 has 1MB of full-speed L2 cache. The FX-57 has increased its transistor size and now has a transistor count of 114 million transistors. AMD has made good use of the increased transistors, providing performance and features unmatched by the current Intel platform. The San Diego core of FX-57 sizes in at 115mm2, on the 90nm and is much smaller than the previous 193mm2 Clawhammer die, which should equate to better yields in AMD's silicon as they also make the move from 200mm to 300mm wafers. The AMD Athlon 64 FX-57 supports all current instruction sets including AMD's proprietary 3DNow!, MMX+, SSE, SSE2, SSE3 and the x86-64 instructions. This brings the technology of the FX-57 inline with all current CPUs available for the desktop market. AMD has given themselves some elbow room as their alternate methodology has panned out for them as Intel hits a brick wall at 3.8GHz.Now while Intel reshuffles their strategy AMD can concentrate a bit more on sheer MHZ power, which will increase the CPUs power even more.
This is a great thing for the overclocker and enthusiast as now the CPU ships unlocked and can handle more system/memory speed increases. This will be more apparent if the CPU is used in conjunction with boards that support the proper voltage adjustments allowing the CPU to remain stable in its enhanced state. With the price of the FX-57 being above the $1031.00 margin, we will have to wait and see whether the performance warrants the grand slam price. AMD a few years back got tired with competing with Intel in the war for the highest clock speed CPU, and started concentrating on better ways to make their lower clocked CPU perform as well as Intel's top of the line standard. They did this by diversifying their technology in different directions in CPU design architecture, and for once the gamble really paid off making AMD the trendsetter and Intel the follower. With strong partners such as NVIDIA and Asus, just to name a few, the AMD platform has come along way. I also prefer the way the heatsink attaches to the Socket 939 motherboards as it offers a much solider and reliable attachment than Intel's LGA775 design. One thing the FX-57 is not is Dual Core equipped; it is however the single core performance dominator, and at a much lower clock speed and temperature range than Intel's 670 3.8GHz Prescott, its one and only competitor. AMD is positioning this CPU as the top of their lineup with a price tag over $1000 USD, which BTW is the highest priced CPU on the market and also one of the highest priced of all time. AMD was the innovator in 64-bit CPUs when they introduced the FX-53 in September of 2003. Today, they have a full line-up of CPUs covering every price range and performance segment. AMD introduced their first Dual Core CPUs, the 4800, 4600 and 4200 a short month ago and will transition their entire lineup to Dual Core later this year. The FX-57 will become obsolete soon as a single core CPU and fade in the wake of dual-core technology, this is quite possibly the last single core chip AMD will produce, but for now it has all the right stuff.
