In CINEBENCH, we see that AMD's initial claims are mostly true, they have closed the gap on single core performance while significantly increasing multi-core performance. In wPrime, we see that Intel and AMD go head to head at eight cores, but we also see how powerful the 3900X is in multithreaded workloads. FPU tests show that floating point, and integer performance at the same core count still is with Intel.

In memory bandwidth, we see something odd, the write speed of AMD's 3700X, and that's because of the CDD to IOD connection, where the writes are 16B/cycle on the 3700X, but it's double that on the 3900X. AMD said this let them conserve power, which accounts for part of the lower TDP AMD aimed for. AMD says applications rarely do pure writes, but it did hurt the 3700X's performance in one of our benchmarks on the next page. Memory latency is a bit high at stock, but you can overclock the memory quite easily.
