We start off with Cinebench R11.5, a good benchmark from Maxon. Based on their Cinema 4D R11.5 3D Digital Content Creation suite, Cinebench tests ray-trace rendering (CPU) and OpenGL rendering (GPU).

As you can see, in conventional Whetstone iSSE3 test, the Intel Xeon E3-1280 peaks out at 85.64GFLOPS, with quite efficient 21.98MFLOPS achieved in a single cycle.
Situation changed in Multimedia test. While the standard Whetstone iSSE3 peaked at 85GFLOPS, MultiMedia Float x16 iAVX test scores 114.65 GFLOPS (Single Precision). Since Single-Precision peaked at 114.65, we expected to see Double Precision to be around half as much. E3-1280 pulls in a nice surprise with 65.2 GFLOPS, i.e. 57% - a nice 7% boost over expected.
Intel's hardware support for cryptography in the form of AES256 yields nice results - 2.38GB/s in standard cryptographic bandwidth, yet AES256 test increases that to 5.27GB/s. Encryption tops as 1GB/s, though.
