Advantages of DDR600 in Athlon 64 Systems
Of course, the frequency of DDR600 memory modules does look very impressive. However, impressive and efficient are not always synonyms. As far as we know from other test sessions and experiments, lower memory latency is much more important for Athlon 64 systems than high memory working frequency. That is why it would still be a question whether DDR600 can be regarded as a good choice for Athlon 64 platforms.
In order to make all your doubts and concerns vanish, we decided to carry out a small investigation. Within this test session we compared the performance of Athlon 64 3800+ on Venice core with DDR600 SDRAM and DDR400 SDRAM. These are the combinations we tested:
- Athlon 64 3800+ working as 12 x 200MHz, memory working synchronously as DDR400 SDRAM;
- Athlon 64 3800+ working as 8 x 300MHz, memory working synchronously as DDR600 SDRAM;
- Athlon 64 3800+ working as 8 x 300MHz, memory working with the divider set to 3:2 as DDR400 SDRAM.
The platform used this time was exactly the same as the one we have just described when talking about overclocking tests. There was only one small difference: during our tests we also used Corsair TWINX1024-3200XL memory modules to obtain the results for DDR400 SDRAM.
So, here are the results:
