QL-65 vs C-70 specifications comparison

The charts below show the difference between C-Series C-70 and AMD Athlon 64 X2 QL-65 most important features. These characteristics, together with an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Operating frequency" graph uses dark color to represent base frequency, whereas lighter area is for additional frequency, provided by Turbo feature. Darker area on the "On-chip cache" graph is for the On-chip L1 cache. Lighter area is for the L2 cache cache. Although the L2 cache cache is usually larger than the On-chip L1 cache, it is always slower.

CPUIDs

The table below compares support for x86 extensions and technologies, as well as individual instructions and low-level features of the AMD Athlon 64 X2 QL-65 and AMD C-Series C-70 microprocessors. Information in this table was retrieved from actual processors using CPUID instruction, and we also utilized internal timer to measure CPU frequency. Be aware that all technologies, disabled in BIOS or by a virtual machine, will be shown as not supported. In rare cases, measured frequency may differ from official specifications.

Commentin Toshibaspeed seems paltry, but is actually pretty stout for something so small and cheap, and the onboard GPA Radeon 7290 HD graphics aren't too bad either. Better buy than the intel version of the acer aspire one 725-0687 netbook
