A leaked slide unveils some of the features of Intel's upcoming Bloomfield processor and the X58 Express chipset (formerly known as Tylersburg).
The Bloomfield will be a 45nm processor with 4 cores and 8 processing threads, SMT (Simultaneous Multi-Threading), 8MB shared L3 chache, an integrated memory controller with 3-channel DDR3 support, Intel QPI (much more bandwidth than FSB) and seven new SSE4 instructions. The X58 will support dual x16 PCI Express 2.0 or four cards at x8.
The slide indicates triple-channel DDR3 memory will have a memory bandwidth of up to 32GB/s, that's almost 30 percent more bandwidth than the 25.6GB/s of the X48 chipset's dual channel DDR3.
Also mentioned in the slide is that the platform will offer physics engine scaling for ultra realistic environments. This could mean Intel's upcoming Nehalem platform may have hardware support for physics processing.
