- Is the 9995WX faster than the 7995WX?
- On paper yes, mainly through clocks: 5.4 GHz boost versus 5.1 GHz, plus DDR5-6400 versus DDR5-5200 memory support. Core count, threads and L3 cache are identical, so gains will be modest in most workloads.
- Do they use the same motherboard?
- Yes. Both are sTR5 chips with PCIe 5.0 and 8 memory channels, so they fit the same workstation boards. Check your board's CPU support list and BIOS version before installing either.
- Which is better for rendering and simulation?
- Both have 96 cores and 192 threads, so multi-threaded rendering and simulation scale similarly. The 9995WX's higher boost and faster memory give it an edge in memory-bound and lightly threaded parts of the job.
- Does either come with a cooler?
- The 7995WX is listed as WOF, without a cooler. Plan on a workstation-class cooler for either chip, since both are rated at 350W TDP.
- Is the 9995WX worth the extra money?
- Only if the price gap is small. The spec differences are clock and memory speed, not core count, so pay extra only when your workloads are sensitive to those.
- How much memory can they take?
- The 7995WX listing states up to 2 TB of ECC DDR5 across 8 channels. The 9995WX lists 8 DDR5 channels at up to 6400 MT/s; check the board maker's validated capacity.
