DDR-II no athlon64

A AMD está planejando lançar processadores com suporte à DDR-II no fim do ano ou começo de 2005. Lembrem-se que com a controladora de memória embutida no core, não há mais como ter suporte a uma nova tecnologia de memória apenas trocando o chipset.

Aqui vai o que eu achei na net: "Advanced Micro Devices is quietly adding DDR-II support into its upcoming Opteron and possibly Athlon 64 microprocessors that are set to come in a pretty near future, sources familiar with the company’s plans revealed"

"While DDR-II allows higher memory clock-speeds to be achieved, it also has some drawbacks, such as higher latencies and increased costs initially. Since AMD processors usually work better with lower memory latencies, the company has to carefully consider all the pros and cons of DDR-II support. Generally speaking DDR-II should not only give AMD a higher peak memory bandwidth, but also should compensate its cranked up latencies somehow." Hmmmm, naõ tinha pensado nisso ainda.... :?

"n the fourth quarter of the year AMD is releasing its Winchester and San Diego cores for Athlon 64 and Athlon 64 FX/Opteron CPUs. Both cores are made using 90nm SOI fabrication process and incorporate dual-channel memory controllers. The difference between San Diego and Winchester is in the size of L2 cache – 512KB and 1MB respectively." Note a incorporação do SOI e o dual-channel No A64.

"What may seem to be highly possible is that Advanced Micro Devices may add support for 533MHz, 667MHz and 800MHz speed flavours of DDR-II, but not to cope with 400MHz bin. “667MHz may be considered as a good option, keeping in mind its speed, latencies and costs” a source close to the Sunnyvale, California-based chipmaker noted."
