The pixel fillrate can be linked to the number of ROPs for some GPUs, but it’s been limited elsewhere for years for many Nvidia GPUs. Actually, most people got those numbers wrong as Nvidia is not crystal clear about those kind of details unless you ask very specifically. Damien graciously agreed to let me publish his explanation:įor a while, I've thought I should drop you an email about some pixel fillrate numbers you use in the peak rates tables for GPUs. He offered a clear and concise explanation for these results-and in the process, he politely pointed out why our numbers for GPU fill rates have essentially been wrong for a while. Then, last week, an email hit my inbox from Damien Triolet at, one of the best GPU reviewers in the business. I promptly raised an eyebrow upon seeing these results, but I didn't have time to investigate the issue any further. Look at what happened, however, when I ran that synthetic fill rate test:ĭespite having superior or equal numbers on paper, the Asus Strix 970 couldn't come close to matching the GTX 980's delivered pixel throughput. The 3DMark color fill test we use has evidently been limited by memory bandwidth at times in the past, but that shouldn't be an issue since all three cards in question have the exact same memory config.

The card measures 145 mm in length, and features a single-slot cooling solution. GeForce GTX 750 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. Display outputs include: 2x DVI, 1x mini-HDMI 2.0. The GPU is operating at a frequency of 1020 MHz, which can be boosted up to 1085 MHz, memory is running at 1253 MHz (5 Gbps effective).īeing a single-slot card, the NVIDIA GeForce GTX 750 does not require any additional power connector, its power draw is rated at 55 W maximum. NVIDIA has paired 1,024 MB GDDR5 memory with the GeForce GTX 750, which are connected using a 128-bit memory interface. It features 512 shading units, 32 texture mapping units, and 16 ROPs. Unlike the fully unlocked GeForce GTX 750 Ti, which uses the same GPU but has all 640 shaders enabled, NVIDIA has disabled some shading units on the GeForce GTX 750 to reach the product's target shader count. The GM107 graphics processor is an average sized chip with a die area of 148 mm² and 1,870 million transistors. Even though it supports DirectX 12, the feature level is only 11_0, which can be problematic with newer DirectX 12 titles. Built on the 28 nm process, and based on the GM107 graphics processor, in its GM107-300-A2 variant, the card supports DirectX 12. The GeForce GTX 750 was a mid-range graphics card by NVIDIA, launched on February 18th, 2014.
