NVIDIA GeForce GTX 750 Ti Maxwell GPU Review
GeForce GTX 750 and 750 Ti Cards
In addition to an NVIDIA reference GeForce GTX 750 Ti, we got our hands on a trio of cards from EVGA and Zotac for the purposes of this review, including a GeForce GTX 750 “non-Ti”.
Before we take a look at the retail-ready cards though, we should discuss NVIDIA’s reference specifications a bit. NVIDIA calls for a base GPU clock of 1020MHz and boost clock of 1085MHz on both the GTX 750 Ti and GTX 750. The memory clock on the Ti is set for 5400Gbps, while the standard GTX 750 comes in at 5000Gbps.
The GeForce GTX 750 Ti features the GM107’s full complement of 640 CUDA cores (1 GPC, 5 SMs), with 40 texture units and 16 ROPs. The GPU is linked to 2GB of GDDR5 memory via a 128-bit interface. With those specification, the GeForce GTX 750 Ti offers up 40.8 Gigatexel’s of fillrate and 86.4 GB/s of peak memory bandwidth. The GeForce GTX 750 has one SM disabled, for a total of 512 CUDA cores, 32 texture units, and 16 ROPs. It offers up 32.6 Gigatexel/s of fillrate and 80 GB/s of peak memory bandwidth.
The Zotac cards featured below are clocked at NVIDIA’s reference specifications. The EVGA GeForce GTX 750 Ti ACX FTW, however, is a factory overclocked model with a number of other customizations as well.
As you can see, the EVGA GeForce GTX 750 Ti ACX FTW features a much larger cooler than NVIDIA’s reference card. More specifically, it’s an iteration of EVGA’s ACX cooler, and like the larger model used on more powerful cards like the EVGA GeForce GTX 770 ACX, it features dual-fans and a large fin-stack, for increased cooling performance. The EVGA GeForce GTX 750 Ti ACX FTW also features a supplemental power connector, which can supply additional power to aid overclocking, and unlike reference cards, the outputs on EVGA’s offering include a DisplayPort, so the card is G-SYNC ready. EVGA’s PCB is slightly longer too, though the cooler extends outward even further.
EVGA has outfitted the GeForce GTX 750 Ti ACX FTW with the same 2GB of GDDR5 memory clocked at 5400 MHz (5400 GBps effective data rate) as reference models, but the card’s GPU is bumped up quite a bit. EVGA has set the base clock at 1189 MHz with a boost clock of 1268 MHz, however, which is significantly higher than NVIDIA’s reference spec. All told, EVGA has essentially upgraded everything about the GTX 750 Ti. More power, more cooling, more flexible output configuration, higher clocks, and it's more menacing too.
We’ve only got one set of pictures here showing off Zotac’s GeForce GTX 750 Ti, but we tested a standard GTX 750 as well—both cards look identical, hence the single set of pics.
Zotac’s GeForce GTX 750 Ti and GTX 750 conform to NVIDIA’s reference specifications, and they sport the same small 5.75” PCB too. Zotac saw fit to incorporate a larger cooler than the reference model, however. The GeForce GTX 750/750 Ti doesn’t need the larger cooler, but it’s a welcome addition nonetheless. Zotac’s cooler proved to be quietest of the bunch throughout testing and the additional cooling capacity should aid in overclocking too.
The Zotac GeForce GTX 750 Ti and GTX 750 both feature a pair of DVI outputs and a single mini-HDMI output, so no G-SYNC here, but that’s not a big deal in this segment. And because the cards don’t stray from NVIDIA’s reference spec, they don’t require any additional power.
