Guys over at WCCFtech found a leak at Vietnamese site, which posted some photos from NVIDIA’s press conference, where first Maxwell-based graphics cards were shown.
This is probably the most official leak in the history of computer graphics. Someone was probably invited to the special press meeting for editors who signed NDA. Apparently one of them cannot read and decided it’s a good idea to post the photos.
First up the official specs of both Maxwell cards.
GeForce GTX 750 Ti
The GTX 750 Ti will use full GM107 GPU with 640 CUDA cores, 40 TMUs and 16 ROPs. It has 2GB GDDR5 memory and 128-bit interface. It will ship with 5400 MHz memory clock. Official TDP for 750 Ti is 60W.
Card is clocked at 1020 / 1085 MHz for base and boost respectively. GTX 750 Ti supports GPU Boost 2.0.
GeForce GTX 750
The non-Ti version arrives with 512 CUDA cores, 32 TMUs and 16 ROPs. It has 1GB memory and 128b interface. The memory is clocked lower than 750 TI (although some documents claim it has the same clock) — 5GHz. The GTX 750 has a TDP of 55W.
You won’t need any power connector for both cards.

|GPU Config||768 : 64 : 16||640 : 40 : 16||512 : 32 : 16|
|GPU Clock||928 MHz||1020 / 1085 MHz||1020 / 1085 MHz|
|Memory Clock||1350 MHz||1350 MHz||1250 MHz|
|Video Memory||1GB GDDR5||2GB GDDR5||1GB GDDR5|
GeForce GTX 750 TI and GTX 750 will replace GTX 650 Ti. The GTX 650 non-Ti will still be produced.
Tell me in the comments if you’re interested in gaming performance of GTX 750 Ti, then I will make a separate post.
For your viewing pleasure I enhanced the photos a bit. Those slides confirm everything I’ve told you in my previous post about Maxwell architecture.
