![]() NVIDIA has taken notice of the boom in Mini-ITX gaming PCs and think that the GeForce GTX 750 Ti is a perfect match for someone looking to build a 1080P small form factor (SFF) gaming PC as you need just a 300W power supply and there is no 6-pin power connector needed on the GeForce GTX 750 Ti reference card. NVIDIA believes that the GeForce GTX 750 Ti will be about a 2x performance upgrade at a fraction of the power use for those still using a GeForce GTX 550 Ti video card from 2010. ![]() NVIDIA says that gamers generally upgrade their video card on every four years on average and that the new GeForce GTX 750 Ti will give those people a huge boost in power efficiency. The really cool thing is that NVIDIA’s GM107 has higher performance specs and has a slightly lower TDP even though it has 570 million more transistors at the same 28nm manufacturing process! The NVIDIA GK107 ‘Kepler’ GPU had just 384 CUDA cores with 1.3 billion transistors and a die size of 118mm 2. The GM107 ‘Maxwell’ GPU has 640 CUDA cores with 1.87 Billion transistors and a die size of 148mm 2. Here is a nice table that shows a high-level comparison of the GM107 Maxwell GPU versus the previous generation Gk107 Kepler GPU. This allows them to to better control the CUDA cores on each particular Maxwell GPU and really helps improve the efficiency. The image above shows a very high-level block diagram that highlights the fact that NVIDIA greatly reduced the shader block sizes into smaller clusters with added control logic. Maxwell logic is better so they can control more cores controls fewer cores. Added more control logic to the CUDA cores. Maxwell has 135% more performance per core and twice the performance per watt. NVIDIA has taken everything they’ve learned from their Tegra line of mobile processors and the Kepler desktop and enterprise processors and put all that expertise to good use in Maxwell. Kepler was on manufactured on the 28nm process and was essentially an upgrade from the previous Fermi architecture that was done on the 40nm process node. Kepler was revolutionary for performance per watt when it came out and so it Maxwell. NVIDIA says that the Maxwell architecture used on the new GM107 (the GPU core used on the GeForce GTX 750 and 750 Ti) has allowed them to produce the most efficient GPU ever built. NVIDIA heavily focused on performance per watt with Maxwell and it clearly shows as the GeForce GTX 750 Ti 2GB video card measures just 5.7-inches in length with a tiny heatsink and doesn’t require any internal power connectors! NVIDIA has been developing Maxwell for a number of years and have decided to launch entry-level discrete graphics cards with the new technology first in the $119 to $149 price range. NVIDIA today announced the new GeForce GTX 750 Ti and GTX 750 video cards, which are very interesting to use as they are the first cards based on NVIDIA’s new Maxwell graphics architecture. The GTX 750 Ti produced a frame rate of 91.6fps when reduced the graphics quality to High, which is higher than the Radeon R7 260X’s 85.6fps average frame rate.NVIDIA GeForce GTX 750 Ti 2GB Video Cards Arrive This is a little lower than the 53.7fps produced by the Radeon R7 260X, but not much. The GTX 750 Ti produced an average frame rate of 48.8fps in Dirt Showdown at a resolution of 1,920×1,080 with Ultra quality graphics and 4x anti-aliasing. The GTX 750 Ti is also just 145mm long, making it 25mm shorter than the miniscule R7 260X. ![]() The AMD Radeon R7 260X, the GTX 750 Ti’s closest rival, requires a 6-pin PCI-E power connector. You’ll only need a 300W power supply and a free x16 expansion slot to use the GTX 750 Ti. Remarkably, the GTX 750 Ti requires just 60W of power to operate, which means it can be powered entirely by the PCI Express x16 bus. The graphics processors in each card Nvidia’s new Maxwell architecture, which Nvidia claims will provide 135 per cent increase in performance per core over the old Kepler-based graphics processors, along with twice the performance per watt. The graphics processor of each card runs at the same speed, though, with a base clock speed of 1,020MHz and a boost clock speed of 1,085MHz. The GeForce GTX 750 has 512 CUDA cores at its disposal, along with 1GB of memory running at 5Gbit/s, while the GTX 750 Ti has 640 CUDA cores, 2GB of memory and memory running at a slightly faster 5.4Gbit/s. ![]() The difference between the two is the amount of CUDA cores used by the cards, memory speed and the amount of memory. The Nvidia GeForce GTX 750 Ti is one of Nvidia’s two new low-cost graphics cards, the other being the GeForce GTX 750. ![]()
