AMD Intros Phenom X4 Stepping B3 & Phenom X3
Advanced Micro Devices, the world’s second largest maker of x86 central processing units (CPUs), unveiled this week its new quad-core AMD Phenom X4 microprocessors that lack the well-known TLB erratum and also boast higher clock-speed compared to predecessors, thus, providing higher performance and efficiency.
As expected, AMD unveiled AMD Phenom processors 9550 (2.20GHz), 9650 (2.30GHz,), 9750 (2.40GHz) and 9850 Black Edition (2.50GHz) which feature 2MB of level two cache (512KB per core) as well as 2MB of level-three cache. All the chips utilize B3 stepping of the core that lacks TLB erratum present on B2 stepping central processing units. All the new microprocessors have 95W thermal design power (TDP), except model 9850 Black Edition and certain versions of model 9750, which have TDP of 125W.
The most important thing is that AMD have adjusted their price policy in a very smart way. Namely, the official price for AMD Phenom X4 9850 Black Edition processor is set at $235, which is less than what the cheapest quad-core Intel processor is currently selling for. AMD Phenom X4 9750 will be offered for $215, while the youngest model – Phenom X4 9550 – is priced at $195.
Besides, AMD also officially announced their triple-core processors known as Toliman. At this time they will only be distributed among AMD OEM partners and will not get into retail.
