Introduction

NVIDIA just launched the new entry-level video card of the GeForce GTX 900 series, the GTX 950. It is based on the GM206 chip, coming with 768 processing cores, 128 bit memory bus and DirectX 12.1 support. We analyzed the Gigabyte N950WF2OC-2GD, which has 2 GiB memory running at 6.6 GHz and factory overclocked to 1,279 MHz. Let’s see how it performs against the Radeon R7 370.

As we mentioned, the graphics chip of the GeForce GTX 950 is the GM206, the same found on the GeForce GTX 960. The GeForce GTX 950 has eight SMM (Streaming Multiprocessor Maxwell) units, each one with 128 processing cores (for a total of 1,024 cores), while on the GeForce GTX 950, two of those units are disabled and, therefore, there are 768 processing cores.

The standard clock of the GeForce GTX 950 chip is 1,024 MHz with boost clock of 1,188 MHz, and memory running at 6.6 GHz. However, it is very hard to find nowadays a video card with standard clocks; we ran this test with a Gigabyte card, model N950WF2OC-2GD, which has a 6.6 GHz memory, but a 1,102 MHz base clock and 1,279 boost clock (about 7.6% overclocking). So, you need to keep in mind that the results we obtained are valid only for the tested card; other cards based on the same chip but with different clocks may have slightly different performances.

According to NVIDIA, the GeForce GTX 950 (reference price of USD 160) has the Radeon R7 370 (reference price of USD 150) as a direct competitor. The GeForce GTX 950 occupies the price position formerly occupied by the GeForce GTX 750 Ti, which had a price reduction for the USD 110 baseline.

For this roundup, we tested the GeForce GTX 950 in several games, comparing it to the Radeon R7 370 (model R7-370P-2SF5 from XFX), and to the GeForce GTX 750 Ti reference board. This Radeon R7 370 also have a small GPU factory overclocking, since its standard clock is 9750 MHz, and the tested card uses a 995 MHz clock (about 2% overclocking).
