For a while now we have been waiting for AMD to refresh its 4200 and 6200 Opterons. Last week details of two new Opteron 4200 models, 4240 and 4276 HE were made public.

CPU World has now spotted these SKUs, as well as four other upcoming chips from 4200 and 6200 series in several US online stores.

Pre-order prices range from $344 to $490 for 4200-series Opterons, and from $693 to $1364 for 6200-series CPUs. Also in the listings are three other SKUs that no one has heard of. These are the Opteron 4230 HE, 6278 and 6284 SE. CPU World thinks that the Opteron 6230 HE could be a consumer version of embedded microprocessor which had had the same model number.

AMD Opteron 6278 and 6284 SE are sixteen-core processors with 16 MB L3 cache, and 115 Watt and 140 Watt TDP. Model 6278 has a 2.4 GHz base frequency, and 6284 SE works at 2.7 GHz. Twelve-core Opteron 6230 HE was planned for the first quarter 2012 as an embedded processor. AMD 4230 HE is a 65 Watt mid-power model with six CPU cores, and 8 MB L3 cache. This Opteron has a 2.9 GHz frequency, which is only 100 MHz faster than currently produced 4228 HE.
