We’re only fascinated by the comparison to GT 1030 because of their similar transistor counts. GeForce GT 730: The Real Competitionīut remember that GTX 750 Ti launched as a $150 card, and even now sells for $100 and up. Of course, a 64-bit aggregate memory bus cripples GT 1030’s peak bandwidth to 48 GB/s using 6 Gb/s GDDR5 GTX 750 Ti’s wider interface facilitates up to 86.4 GB/s. In contrast, GeForce GTX 750 Ti starts at 1020 MHz and boosts just slightly to 1085 MHz.
Our sample employs a 1227 MHz base frequency and a typical GPU Boost rating of 1468 MHz. Nvidia goes a long way to overcoming those deficits in GT 1030 with higher clock rates. That’s a lot of lost resources for a ~4% difference in complexity. And whereas GeForce GTX 750 Ti utilizes two 64-bit memory controllers, GT 1030’s specs break the memory bus down into a pair of 32-bit controllers, adding up to a 64-bit interface. That means GeForce GT 1030 includes 512KB L2 total-a big reduction from GTX 750 Ti’s 2MB. However, those partitions are aligned with 256KB slices of L2 cache on GP108 and 1MB slices of L2 on GM107. The two GPUs feature a pair of ROP partitions, giving you up to 16 32-bit integer pixels per clock. Both designs also expose eight texture units per SM, totaling 24 on GeForce GT 1030, while GTX 750 Ti gets 40. Given 128 CUDA cores per SM/SMM in the Pascal and Maxwell architectures, that’s 384 cores for GT 1030 and 640 for GTX 750 Ti. Here’s the thing, though: whereas GeForce GTX 750 Ti employs five Streaming Multiprocessors, GT 1030 comes equipped with three.
Or how about the GeForce GTX 750 Ti, which we’re making the GT 1030 battle in today’s benchmarks? That card’s GM107 GPU has a similar transistor count as GP108, but in a 148mm² die, owing to its 28nm manufacturing process. Compare that to GeForce GT 730’s GK208 chip with 1.02 billion transistors in an 84mm² die. It’s a teeny thing at just 70mm², thanks to the same 14nm FinFET process used to manufacture GP107.
GeForce GT 1030 utilizes an all-new graphics processor called GP108, composed of 1.8 billion transistors.
