L4 Cache does improve DF performance, at least in worldgen.
« on: November 03, 2020, 12:51:45 am »

A recent Anandtech article revisited the Intel Broadwell-DT processors using their current testing methodology. These tests include the DF 44.12 worldgen tests, testing worldgen at 65x65 250 years, 129x129 550 years, and 257x257 550 years. Further details can be found in the linked article. The interesting thing is that the Broadwells tested have 128 MB of eDRAM acting as L4 cache. Combined with the DF tests, I'd like to bring up a point:




(Source)

The CPUs with L4 cache are the i7-5775C and the i5-5675C in light blue and blue respectively. It would seem that with the cache, even the i5-5675C is able to outperform an i7-6700K in all three tests, which is a year newer than the i5. It manages to offset the RAM speed disadvantage, considering that the 5675C ran DDR3-1600, and the 6700K ran DDR4-2133.

Consider how close these CPUs are to the top. The i7 is impressive, managing to trail slightly behind the i5-10600K in the first and third test, and actually beating it in the second test. Keep in mind, this i7-5775C is 5 years older than the i5-10600K, and it runs on an older architecture than the i5-10600K (the former runs on Haswell, the latter on Skylake). Not only that, the i7-5775C can boost up to 3.7 GHz, and the i5-10600K boosts up to 4.8 GHz, so even with the clock speed disadvantage, it manages to do very well.

That's all I can really say about this. It's an interesting point, if anything.
