Intel Core i7-5960X
Intel's first eight-core, sixteen-thread desktop CPU and the $999 halo of the X99 platform, trading clock speed (3.0 GHz base, 3.5 GHz turbo) for core count. It is a used-market or enthusiast-nostalgia buy now, and it only makes sense if you intend to overclock it.
Pros
- 8 cores / 16 threads, still enough for light rendering, encoding and virtualisation workloads
- 20 MB L3 and quad-channel DDR4 — the most cache and bandwidth of any Haswell-E part
- 40 PCIe 3.0 lanes direct from the CPU
- Fully unlocked; 4.2-4.4 GHz all-core overclocks were common with strong cooling
- Costs a small fraction of its $999 launch price on the used market
Cons
- 3.0 GHz base and 3.5 GHz turbo mean stock single-thread performance is poor by any modern standard
- 140 W rated, but overclocked all-core loads push well past 200 W and demand a 240 mm AIO or better
- Official DDR4-2133 support with a 64 GB ceiling, and eight DIMMs of DDR4 to buy used
- Dead platform: no PCIe 4.0, no modern power management, and X99 boards are used-only with ended BIOS support
