- It seems, K9 will have an integrated DDRII controller
- Processor will feature speculative branching (up to 8 branches), and probably some rollback cache in case a branch is predicted wrong...
- Processor will probably have 3 (!) fully-fledged х87 blocks, 3 SSE2 and 2 ALU blocks. Decoders will be capable of organizing them by three (FPU + SSE2 + ALU) for maximum performance.
- K9 will possibly utilize AMD’s old patent, describing integrated Peltier element packaging
- Processor might have several buffers, a kind of L0 cache. For example, a 4Kb buffer will precede and follow FPU for making its operation (SSE2, 3DNow) continuous.
- К9 might also support L3 cache for commented code. I.e. decoder will be capable of acting right in L3 inserting comments into special fields.
- Pipeline will probably feature 15 ALU stages, 20 FPU stages.
- I-cache and decoder will perform at double speed.
- AMD might situate L3 cache on crystal using 1T-SRAM.
- Hyper Transport II – expected to be something like Octal Data Rate (Yellowstone) with about 1GHz carrier clock. As a result throughput will reach 25Gb/s in 16x16 configuration.
- Interprocessor protocol (MOESI) will be updated and improved.
- The very fast bus will provide a very interesting feature of sharing free executive units between two processors. I.e. if the first has FPU loaded and the second has it free, then the latter can handle requests from the decoder of the former.
펠티어소자를 쓴다는 내용도 있고, 파이프라인을 15 ALU/20 FPU로 만든다는 내용도
DDR2를 지원한다는 내용이 있습니다.
