AMD Opteron 4274 HE vs 6174

Mini Review

AMD Opteron 4274 HE advantages

  • Operating frequency of the microprocessor is higher than the frequency of the AMD Opteron 6174.
  • The AMD Opteron 4274 HE has SSSE3, SSE4.1 and SSE4.2 instructions enabled.
  • The CPU incorporates AES instructions, that accelerate AES encryption. The technology is useful if you need to secure your disk or network data.
  • The AMD Opteron 4274 HE microprocessor includes AVX and XOP instructions, that were introduced in the recent past. These extensions are not extensively used by programs yet, but their support should improve in future apps.
  • The 4274 HE has FMA4 instruction set extension enabled. Only AMD processors have this technology, therefore not many software vendors may support it in the future.
  • Power consumption of the CPU is lower.
  • Based on current official prices, the AMD 4274 HE is 68% cheaper.

AMD Opteron 6174 advantages

  • The AMD 6174 incorporates more processing cores than the AMD 4274 HE microprocessor. Large number of cores helps this processor to tackle multiple tasks or heavily multi-threaded programs.
  • The Opteron 6174 includes 3DNow! technology. These instructions can boost performance of certain old games. The 3DNow! set was depreciated, and not used in modern applications.

4274 HE vs 6174 specifications comparison

The charts below compare the most important characteristics of the 6174 and AMD 4274 HE CPUs. These features, along with an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for extra frequency, provided by Turbo feature. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. While the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.
