Specifications and Recommended Price
The specs and recommended price of Nvidia’s GeForce GTX 750 Ti and GTX 750 cards are listed in the table in comparison with the reference cards Nvidia GeForce GTX 650 Ti Boost, Nvidia GeForce GTX 650 Ti and AMD Radeon R7 260X:
PCB Design and Features
The reference Nvidia GeForce GTX 750 Ti is only 145 mm long, just like its predecessor GeForce GTX 650 Ti.
The new card is somewhat slimmer at 34 mm:
There are no differences in terms of video outputs: dual-link DVI-I and DVI-D ports and a mini-HDMI 1.4a.
The 6-pin power connector has disappeared from the PCB although there is a contact pad for it there:
It might be expected since the specified power draw of the GeForce GTX 750 Ti is only 60 watts as compared to the GTX 650 Ti’s 110 watts. Thus, the new card can be easily powered via a mainboard’s PCI Express slot that can deliver up to 75 watts. A 300W PSU is recommended for a computer with one such graphics card. The GeForce GTX 750 Ti doesn't support SLI technology.
The new card is based on the PCB from the GeForce GTX 650 Ti.
The power system has two phases for the GPU and one phase for the memory chips and PLL.
The GM107 Maxwell die is only 148 sq. mm large and lacks a protective frame. We guess, however, that off-the-shelf products will have that very useful element, which has been present on them since the GTX 650 Ti.
The GPU chip is revision A2 and, judging by its marking, was manufactured on the 49th week of 2013 (in early December). The base clock rate in 3D applications is 1020 MHz. It can be boosted to 1085 MHz but, according to our monitoring tools, the top frequency is 1163 MHz. The voltage is 1.168 volts but off-the-shelf samples of the card may have a different voltage. In 2D mode the GPU clock rate is dropped to 135 MHz (and not to 324 MHz as with the GeForce GTX 650 Ti) whereas the voltage is lowered to 0.95 volts.
The ASIC quality of our sample of the GeForce GTX 750 Ti GPU is 74.0%:
The Nvidia GeForce GTX 750 Ti is equipped with 2 gigabytes of GDDR5 memory in SK Hynix’s FCBGA-packaged H5GC4H24MFR-T2C chips:
The chips are rated for 5000 MHz at 1.35 volts or 6000 MHz at 1.5 volts. The GeForce GTX 750 Ti seems to use the latter variant, clocking its memory at 5400 MHz. The peak bandwidth across the 128-bit bus is 86.4 GB/s, so the new card is no different from the GeForce GTX 650 Ti in terms of its memory subsystem.
The latest version of GPU-Z is already familiar with the GeForce GTX 750 Ti:
