“Has AMD begun shipping its Athlon 64 4200+ to OEMs? Apparently so, if leaked processor specification screengrabs posted on a Chinese web forum are genuine.
The shots, initially posted on Digital-Info and re-published on XtremeSystems, purport to show the 4200+ up and running. Unfortunately, the test utility CPU-Z reports the chip as an Athlon 64 2200+, but the 2.6GHz clock speed, 1MB of L2 cache and presence of SSE 3 instructions suggest the part is a second-generation 90nm part, codenamed San Diego.”
You can check out Xtremesystems.org for screenshots of CPU-Z, and check out the article where I found this info at The Register.
