Which is why I don't normally run those tasks. Not sure how well it would do with GBT VLARs tho...

Probably even worse.
Celeron flawed by cache size first hand. And VLAR (GBT including) needs semi-random access to largest arrays in whole algorithm.

In this CPU cache is split between cores. Each 2 cores get 1MB cache. Instead of a single large L3 cache line in Core ix CPUs., but the split cache might be the reason it didn't suffer CPU slow downs when running iGPU MB tasks like Core ix CPUs tend to show.
I like having different types of hardware to see how the design changes effect our crunching.
I really want to get a CPU with Iris Pro graphics to see how an iGPU with its own cache handles things. However they tend to be hard to find or cost much over list prices.

In an interesting turn of events. The GTX 950M in my new notebook is the same GM107 configuration, with a slightly lower GPU clock, as the 750Ti . Paired with a much faster CPU, 3.3GHz i7, the CPU time for tasks is a bit lower, but tasks time is about as expected for the GPU.
