Tesla C2xxx vs GTX 4xx differences beside cores / memory / clock speed

Accelerated Computing CUDA CUDA Programming and Performance
#1

I was wondering how many of the features from page 2 of the Tesla fact sheet (except those in topic description) were also shared by the GTX line?
Specifically:

  • NVIDIA PARALLEL DATACACHE
    Accelerates algorithms such as physics solvers, ray-tracing, and sparse matrix multiplication where data addresses are not known beforehand. This includes a configurable L1 cache per Streaming Multiprocessor block and a unified L2 cache for all of the processor cores.

  • NVIDIA GIGATHREAD ENGINE
    Maximizes the throughput by faster context switching that is 10X faster than previous architecture, concurrent kernel execution, and improved thread block scheduling.

  • ASYNCHRONOUS TRANSFER
    Turbocharges system performance by transferring data over the PCIe bus while the computing cores are crunching other data. Even applications with heavy data-transfer requirements, such as seismic processing, can maximize the computing efficiency by transferring data to local memory before it is needed.

You can assume all of them except the double precision performance, which is capped on the Geforce cards (and I think you will find that GTX470 and Telsa C2xxxx/M2xxxx have the same core count).
