I am fairly sure that Nvidia will not be amused with a website called ukgamingcomputers right now, they just posted GeForce GTX 750 & 750 Ti Benchmarks. The new GTX 750 and 750 Ti are the first cards be based on “Maxwell” architecture which is the successor to “Kepler” as we know it. Maxwell will use a 28nm manufacturing process but with later models move down to a 20nm manufacturing process.
The 750 and 750 Ti are of the 28nm manufacturing process. Another interesting feature is neither card has a power connector drawing all the required power from the PCI-E Slot.
Both GTX 750 Ti and GTX 750 seem to be based on a GPU called GM107 a Maxwell graphics processor. The 750 Ti will get 960 CUDA cores, 80 TMUs and 16 ROPs. The card is equipped with 2GB GDDR5 memory and 128-bit interface. In terms of clocks, depending on brand/oem 1050+ MHz. The GTX 750 will get 768 CUDA cores, 64 TMUs and 16 ROPs, with just 1GB graphics memory though.

Anyway, here's that snippet from ukgamingcomputers.co.uk from which you can extrapolate all specs as we just did:
The 750 and 750 Ti are of the 28nm manufacturing process. Another interesting feature is neither card has a power connector drawing all the required power from the PCI-E Slot. Early benchmarks showed the new cards to be a little watered down barely exceeding the performance of a Nvidia GTX 650 of 650 Ti however it was presumed because the drivers were in their early infancy.
Test Setup
Both cards were tested in the same setup;
- Intel Core i7 4770K (stock)
- 8GB Corsair XMS3 RAM
- Asus Z78-K Motherboard
- Windows 8.1
Back in early February when we initially tested the cards, both the new cards would not install with the current latest 332.21 Driver so an older 332.17 had to be used. Interesting to also know is the older GTX 660 and GTX 650 Ti did not install with the 332.17 driver and had to be benchmarked with the latest 332.21 driver so there is some inconstancy with the setup. Another note is that both these new cards are factory overclocked.
So, how do they actually do? The numbers speak for themselves;
| GPU | 3DMark 11 Score |
| Nvidia GTX 750 | 5250 |
| Nvidia GTX 750 Ti | 5963 |
| Nvidia GTX 650 Ti | 4819 |
| Nvidia GTX 660 2GB | 6727 |
It is worth remembering that both the new flavours were tested with an older driver and it was impossible to test all cards on the same driver. No doubt that will impact the performance but over time it is expected Nvidia will be updating drivers that are compatible with GTX 750's and as a result will pull off better 3DMark Scores.
