Sandra’s Arithmetic scores shows off the Core i7-4790K's clock rate advantage in stock form compared to Intel's Core i7-4770K. The new CPU also overclocks better, edging out the good overclock I achieved on the first quarter's $2400 PC and smashing the horrible overclock from Q2, which employed the same CPU model apparently cut from a different part of the wafer.
Sandra Cryptography saw marked improvements too, especially in the bandwidth-sensitive encoding/decoding test. A quick look at bandwidth numbers reveals the reason.
Even though I used the same memory in both the current and previous build, this quarter's PC significantly outpaces Q2’s at stock settings. Use of the same RAM points towards the motherboard as the problem, where MSI and ASRock both beat Asus.
