Beyond dual core: 2007 desktop CPU road map


In the second quarter, Intel plans to release a number of processors in this value category. Around this same time, the chipmaker will probably phase out the Pentium 600 series, specifically the Pentium 4 651, 641 and 631.

To avoid confusing CPU buyers, Intel will use the Pentium and Celeron brand names for these new CPUs, even though they are based on the Core architecture.

In the Pentium bracket, we'll see releases of the E1060, E1040 and E1020. The E1060 will have a clock speed of 1.8 GHz, the E1040 will run at 1.6 GHz, and the E1040 will run at 1.4 GHz. Each will have 1MB of L2 cache with a front-side bus speed of 800 MHz. While these processors will support Intel's 64-bit extensions, none of the E1000 line will support virtualization or hyperthreading, a technology that allows single-core CPUs to behave as if they were dual-core ones.

In the Celeron bracket, CPU buyers will likely see a wide range of clock speeds. At press time, no specific model numbers or clock speeds were available, but it appears that the name of this series of processors will be the Celeron 400 series and that these processors will have 512KB of L2 cache. It is not clear whether or not these processors will support 64-bit extensions, virtualization or HyperThreading.
