AMD Sempron 2800+ & 3100+

Test System provided by AMD


AMD Sempron Socket 754 3100+

The AMD Sempron Socket 754 will eventually replace the socket A Sempron and lead the industry into a stage of budget performance computing. The Sempron speed performance ratings on the socket 754 chips should not be compared to the existing Socket 754 Athlon 64 processors. The Sempron Socket 754 was meant to compete against Celeron chips and are so rated to give an "apples to apples" approach to comparison. An existing AMD 64 3000+ Socket 754 in-house performed slightly better than the Sempron 3100+, due to the lower cache size and the disabled 64 bit ability of the Sempron. Consumers seeking Athlon XP prices with much greater performance due to the added on processor memory controller would do well to check out these processors.

As you can see, the AMD Sempron has some impressive specifications which are nearly identical to its big brother, the AMD 64 Socket 754. The Sempron comes with half the cache and 64-bit abilities disabled, however, it costs only a fraction of the AMD64's price. The performance difference is very slightly in favor of the AMD64, with the Sempron being able to completely handle all 32-bit applications, as the Athlon XP does, but with an increase in memory bandwidth and performance. The decreased cache will hurt the Sempron only slightly in gaming and application performance.

The Test system was configured as follows:

Albatron K8X800 Pro II
2 x 256 Kingston HyperX PC3200 CL 3
AMD64 Sempron Socket 754 3100+

For reasons of fairness, Techwarelabs chose not to compare the Sempron 3100+ scores to the Intel Celeron. As Intel's highest-rated Celeron is 2.8 Ghz, it be unfair to compare it to the 3100+ with the added benefit of an onboard memory controller. Such a comparison would not be an "apples to apples" demonstration and would reflect poorly on the Celeron.

What can the Sempron 3100+ do?
