VIA C7-M Processor
Main Specifications
Contents
The C7-M processor main specs include:
- 90 nm process;
- Low power design (average power below 1 W and 0.1 W when idle with a maximum TDP – Thermal Power Design – of 12 W at 1.5 GHz and 20 W at 2 GHz);
- 128 KB L1 memory cache and 128 KB L2 memory cache;
- External clocks of 400 MHz, 533 MHz and 800 MHz (in the future);
- Two internal clocks (called “TwinTurbo” technology by VIA), the second clock, which is smaller, is used for running the CPU in a low-power state in order to save battery life;
- Integrated security co-processor, called “PadLock”;
- NX bit (prevents virus attacks if you use Windows XP SP2);
- MMX, SSE, SSE-2 and SSE-3 support.
