The Intel Celeron 600 was a desktop processor with 1 core, that was never released. It is part of the Celeron lineup, using the Timna architecture with Socket 370S. Celeron 600 has 128 KB of L2 cache and operates at 600 MHz. Intel is building the Celeron 600 on a 180 nm production process, the transistor count is unknown. The multiplier is locked on Celeron 600, which limits its overclocking capabilities. With a TDP of 30 W, the Celeron 600 consumes only little energy. The highest officially supported memory speed is 400 MT/s, but with overclocking (and the right memory modules) you can go even higher. Actual memory technology support depends on the chosen motherboard, the processor itself supports multiple memory types, but most motherboards have only one kind of slot. For communication with other components in the system, Celeron 600 uses a PCI-Express N/A connection. This processor features the Intel i752 integrated graphics solution. Many games will refuse to start on this processor due to the lack of the SSE2/SSE3/SSE4 instruction set.
"Timna" was cancelled in 2000 but engineering samples were produced and distributed in small quantities along with sample platforms featuring both RDRAM and SDRAM variants.
The processor die featured a sophisticated integration of a RDRAM memory controller and i752 graphics core as a means to decrease board complexity and cost. SDRAM boards were possible with the use of the Intel MTH translator chip which incurred a large performance penalty but further decreased cost at the time.
