Radeon R9 270 vs GeForce GTX 970M comparison

According to the hardwareDB Benchmark, the GeForce GTX 970M GPU is faster than the Radeon R9 270 in gaming.

In our comparison, the GeForce GTX 970M has a slightly higher core clock speed. This is the frequency at which the graphics core is running at. While not necessarily an indicator of overall performance, this metric can be useful when comparing two GPUs based on the same architecture. In addition, the GeForce GTX 970M also has a slightly higher boost clock speed. The boost clock speed is the frequency that the GPU core can reach if the temperature is low enough. The allows for higher performance in certain scenarios.

Furthermore, the spec sheet for both these GPUs show that the GeForce GTX 970M has significantly more memory with 3 GiB of memory compared to 2 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

In addition, the GeForce GTX 970M has a significantly lower TDP at 75 W when compared to the Radeon R9 270 at 150 W. TDP (Thermal Design Power) measures total heat output from the chip.

In conclusion, all specs and GPU benchmarks considered, will recommend the GeForce GTX 970M over the Radeon R9 270.
