What customers say about "Cache And Memory Specifications"
AMD Athlon II X4 651K CPU Processor
  • Amazing processor, a good L2 cache-4x1MB.
  • Installed 16 GB of RAM, the lack of a level 3 cache is imperceptible.
  • Even 4MB of L2 cannot compensate for the absence of L3.
  • 1333 memory gives a bandwidth of 12GB / s, and this is not the limit, Samsung memory will probably give 20GB / s.
  • No level 3 cache. Useless CPU.
AMD A8-3870K CPU Processor
  • With a Micro ATX-350W power supply with 8Gb DDR3 1600 Mgh RAM, everything just works really fast.
  • 4MB of L2 cache is good for work and gaming.
  • Powerful video chip, very fast memory.
  • The main advantages are the integrated graphics and memory.
  • You need high-quality RAM, without it the processor is useless.
