EVGA GTX 750 TI FTW ACX

The EVGA GTX 750 Ti FTW ACX (02G-P4-3757-KR) is an entry level gaming card. These cards are intended to replace the Geforce GTX 650 series. This card launched at $199 but fell quickly in the market.

  • NVIDIA Maxwell GM107
  • 640 CUDA
  • 1189 MHz base clock
  • 1268 boost clock
  • 2048MB GDDR5
  • 128-bit
  • 5400MHz effective
  • 86.4GB/s bandwidth
  • ACX dual fan cooler
  • PCI Express 3.0 x16
  • DVI-I, HDMI, DisplayPort
  • DX12 (feature level 11.1)
  • OpenGL 4.4
  • 9″ card length

This GPU is NVIDIA’s first Maxwell release. Maxwell is designed to be 2x more efficient per watt over Kepler. Reality is that our EVGA GTX 660 Ti is more than double the performance with less than double the power needed so we question the power efficiency gains of Maxwell. When the GTX 750 Ti is compared to our EVGA GT 640 there are material gains.

Maxwell SM architecture now has five SMs in GM107, compared to two in GK107, with only a 25% increase in die area. Most of the additional area is taken up by the much larger L2 cache.

The new control logic is a redesign over Kepler; Kepler used a large crossbar, Maxwell redesigned it to use way less power. Texture units and FP64 are shared.

A single 128 CUDA core SMM can deliver 90% of the performance of a 192 CUDA core SMX at a much smaller die size.

Maxwell has 32 FP32 CUDA cores in each SMM module. This is smaller than the Kepler which has 192 CUDA per SMK. Kepler has 256KB L2 while Maxwell has 2MB. The improved cache affords 128-bit memory instead of the more demanding 192-bit which reduces power consumption.

  • dle/2D power mode: approx. 355W
  • Blu-ray & DVD playback mode: approx. 13W
  • Full 3D performance mode: varies – worst case TDP 85W
  • 9” length, dual slot

The reference NVIDIA GTX 750 Ti is roughly 1020 MHz  however EVGA was able to achieve 1189 MHz

The TDP of the GTX 750 Ti is 85W due to the overclocked GPU. This means the EVGA card needs a 6-pin power cable connected. The new NVENC logic in Maxwell provides H.264 support with double the performance of Kepler.  For real time applications such as ShadowPlay and GameStream, the benefit will primarily be a reduction in encoding latency by upwards of several milliseconds. For offline video transcoding, the greater throughput should directly translate into faster transcoding.

Maxwell still needs an adequate PSU. We like our Corsair CS450M which can easily handle this card.

Maxwell also features a new GC5 power state that’s been tailored to reduce the GPU’s power consumption specifically for light workload cases like video playback.

GC5 is a low power sleep state that provides considerable power savings over prior GPUs for these scenarios.

Some lower cost models of the GTX 750 TI only have 1024MB but EVGA provides the full 2048MB so that games will run way better. GDDR5 is standard with the Maxwell series.

At idle The EVGA GTX 750 Ti runs at about 28°C which is similar to our EVGA GTX 660 Ti. Loaded the GTX 750 Ti does not get much past 65°C. The EVGA ACX cooler can manage with tropical conditions easily which keeping fan noise well below 38 dBa.

DUAL FAN

EVGA is now using dual fan coolers on many their video cards to keep them running cool. While most of the warm air is exhausted out the rear, some of the warm air from the VRAM is returned to the chassis. The top mounted fans in our Corsair Carbide 300R far exceed the extra thermal load imposed by any graphics cards.

The real immediate advantage is the reduced noise from the cooler fans. Even when loaded 50% the fans often remain at idle. By comparison the old GTX 260 blower fan would howl when the card was running hard.

GAMES

The EVGA GTX 750 Ti FTW ACX can play games at 1920×1080 reasonably well. Graphics settings may need to be reduced  to achieve an acceptable framerate.

7th generation games will run the best on the GTX 750 Ti. The old Xbox 360 GPU is not nearly as powerful. See the page on system requirements.

  • Left 4 Dead 2
  • Batman Arkham City
  • Red Orchestra 2
  • Hawken
  • Deadspace
  • Tom Clancy’s Ghost Recon Phantoms
  • Team Fortress 2
  • Titanfall

More taxing games like Crysis will run at medium-high at 60fps
