The NVIDIA GeForce GTX 750 Ti and GTX 750 Review: Maxwell Makes Its Move
by Ryan Smith & Ganesh T S on February 18, 2014 9:00 AM ESTThe Test
For this review we’re using the latest drivers from both NVIDIA and AMD. NVIDIA’s launch drivers are 334.69, which add support for the GTX 750 series but are otherwise identical to the 334.67 drivers currently available as a public beta for existing cards. The release 334 drivers include a fairly impressive tune up of NVIDIA’s OpenCL stack, so we’re finding that OpenCL performance is significantly improved in some of our benchmarks, which helps to close the gap with AMD. On the other hand these tune-ups have not come bug free (as Ganesh has found), and while our compute benchmarks are fine, Ganesh has run into some issues with some of his OpenCL based video utilities. Other than that, we have not encountered any stability problems with these drivers.
Meanwhile for AMD’s cards we’re using the recently released Catalyst 14.1 beta v1.6 drivers.

20 nm Maxwell will be epic. Gimme.TheinsanegamerN - Tuesday, February 18, 2014 - link
Imagine. OCed Geforce 690 level performance, out of a single chip, with 8 GB of RAM on a 512 bit bus, pulling the same amount of power as a geforce 770. One can dream....ddriver - Tuesday, February 18, 2014 - link
LOL, epic? Crippling FP64 performance further from 1/24 to 1/32 - looks like yet another nvidia architecture I'll be skipping due to abysmal compute performance per $ ratio...JDG1980 - Tuesday, February 18, 2014 - link
This card is designed for gaming and HTPC. Only a tiny fraction of users need FP64.nathanddrews - Tuesday, February 18, 2014 - link
So I guess we'll have to wait for the 750TIB before we can see SLI benchmarks. Two of these would be within reach of 770 while using considerably less power. Hypothetically, that is.ddriver - Tuesday, February 18, 2014 - link
You do realize the high end GPUs on the same architecture will have the same limitation?Morawka - Tuesday, February 18, 2014 - link
I thought the higher end Maxwell cards will have Denver/aRM cores on the PCB as well.Mr Perfect - Wednesday, February 19, 2014 - link
It might be a software/firmware limitation though. From what the compute enthusiasts have said, the only difference between the Titan's full compute and 780Ti's cut down compute is firmware based. They've got the same chip underneath, and some people hack their 780s for full compute. They're probably doing the same thing with the Maxwell stack.chrnochime - Wednesday, February 19, 2014 - link
Got link for the hack? Sounds interesting.Mr Perfect - Thursday, February 20, 2014 - link
I don't myself, but if you're interested look up IvanIvanovich over at bit-tech.net. He was talking about vbios mods and resistor replacement tweaks that can do that.
