Radeon HD 7670M vs Radeon HD 8790M benchmarks

According to the hardwareDB Benchmark, the Radeon HD 7670M GPU is faster than the Radeon HD 8790M in gaming.

The Radeon HD 8790M 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.

As stated by the manufacturer, the Radeon HD 8790M has significantly more memory with 2 GiB of memory compared to 1 GiB. Memory size doesn't directly affect performance, but too little memory will certainly degrade gaming performance.

According to the results of the hardwareDB benchmark utility, the Radeon HD 7670M is faster than the Radeon HD 8790M.
