As we've reported earlier, the 6XX range of processors will have 2MB of level two cache, will have bus speeds of 800MHz, and will also support the firm's EM64T technology.
So far, Intel has only incorporated the 64-bit features of EM64T in its Xeons and in processors designed for workstations.
The chips, which are set to launch next year, are already sampling to customers, and the firm is contemplating releasing them in late February of next year.
The processors will be compatible with the 915/925 Express chipsets and future chipsets codenamed Glenwood and Lakeport. They will also include a better "Halt State" for power management when PCs are idling, and a fresh version of Speedstep technology.
The tech, called the Enhanced Intel Speedstep Technology (EIST), means system noise can be reduced.
That can mean a reduction of power consumption over 5XX chips of up to 15 watters/hr/CPU, Intel is estimating. A big firm that has 10,000 PCs and at an estimated cost of six cents per kilowatt hour, can save $80,000 a year.
The chips which have numbers such as 630, 640, 650, 660 and 670, will be still branded as Pentium 4s but Intel's customers are being advised to push the chips over the current 5XXX range on their increased cache, the inclusion of EM64T, and EIST.
It's even come up with an interesting little line "Adding value beyond GHz", and claims the increased cache size will let game developers use better software physics engines and artificial intelligence.
The firm's presentation shows that compared to a 550 (3.4GHz) Pentium 4 with 1MB L2 cache and an 800MHz system bus, a 650 offers improvements. The 650 is also a 3.4GHz processor with the same bus speed, but with 2MB of cache. It claims that in SPEC_fp base2000, the 650 is six per cent faster, while in SPEC_int base2000, it is seven per cent faster than the 550.
As for EM64T technology, Intel claims there will be benefits both in high quality audio and video processing as well as 3D rendering. µ
