Cheap cheap: AMD Sempron 2600+ S754

While not new, it’s worth mentioning a few words about the “new” Palermo-core Sempron processors that fit into AMD’s Socket 754 socket, which are numbered 2600+, 2800+, and 3000+, respectively.

Interestingly, both the 2600+ and 2800+ models are clocked at 1,6 GHz, while the secondary cache is 128 KB for the slower model and 256 KB for the more powerful model. The processor core is codenamed Palermo, which can be directly derived from AMD Athlon 64 processors from the 90-nanometer Newcastle core.

The "only" difference is that the 64-bit registers were disabled, the size of the second-level cache was reduced by half or a quarter, and the Cool\\"n\\"Quiet function was turned off, by removing the possibility of setting the multiplier from Semprons. Nevertheless, it can be guessed that the average 64-2,30 GHz overclockability of the Newcastle Athlon 2,40 processors has been inherited, since the core is the same and the second-level cache is also much smaller than its big brother, thus suggesting more overclocking "capacity".

Az X-bit labs staff specifically an AMD Sempron 2600+ models were examined. The result is more than surprising, as the processor available for less than HUF 20 gross often left the almost HUF 000 AMD Athlon 70 000+ processor. True, all this at a 64 MHz real clock with a 3500 MHz FSB.

Of course, to achieve this speed, you also need a suitable motherboard under the processor. However, since we can also get it from several manufacturers at a gross price of HUF 20 NVIDIA nForce3 250 motherboards, so we can see that the total cost of 40 forints is not a very high price for such performance. THE VIA and SiS chipset Socket 754 motherboards are not mentioned because unfortunately they become unstable one by one above 280 MHz FSB.
