The new GPUs feature Nvidia’s Maxwell architecture and are so efficient that they do not need a dedicated power connector.
Nvidia launched the GTX 750 and GTX 750 Ti cards today, its new entry-level cards are the first to feature its new Maxwell architecture.
The cards are based on a 28 nm GM107 silicon. The GM107 GPU features five streaming multiprocessors, each containing 128 CUDA cores. While the GTX 750 and 750 Ti feature the GM107 GPU, other cards launched later this year will be based on the smaller GM108. These two will be the only GPUs based on the 28 nm manufacturing process. In the latter half of the year, Nvidia will be shifting to a next-generation 20 nm process, and the first 20 nm cards will feature the GM206, the GM204, and the GM200 GPUs.
Coming over to the GTX 750 and GTX 750 Ti, it is clear that Nvidia was targeting efficiency when designing these cards. These cards do not come with any power connecter, and draw power from the motherboard directly. They are twice as efficient on a performance per watt basis when seen against cards like the GTX 550 Ti. For instance, the GTX 750 Ti requires only 60 watts to run, which is half of the 116 watts that was needed by the GTX 550 Ti.
The GTX 750 features 512 CUDA cores, 32 TMUs, 16 ROPs and memory bandwidth of 5.0 GHz. The card has core clocks of 1020 MHz, boost clocks of 1085 MHz, 1 GB GDDR5 memory on a 128-bit bus interface and a TDP of just 55 watts. It comes with DL-DVI-I, DL-DVI-D and Mini-HDMI connectors.
Meanwhile, the GTX 750 Ti is slightly more powerful, and comes with 640 CUDA cores, 40 TMUs and 16 ROPs. The card features the same clocks as the GTX 750, but comes with twice the amount of video memory at 2 GB running at 5.4 GHz. The GTX 750 Ti has a TDP of 60 watts.
While AMD has rebranded its last-gen HD 7850 and is calling it the R7 265, Nvidia has launched cards that come with a new architecture and are twice as powerful as their last-gen counterparts, which can be clearly seen from the benchmark scores above. And for once, Nvidia has priced its offerings logically, with the GTX 750 set to retail for $119 and the GTX 750 Ti on sale for $149. AMD’s R7 265 will also be available for $150, but it is unlikely it will be able to match the prowess of the GTX 750 Ti. Looks like Nvidia has won this round.
