Radeon R7 M340 vs Radeon R9 280 comparison

According to the hardwareDB Benchmark, the Radeon R9 280 GPU is faster than the Radeon R7 M340 in gaming.

Our database shows that the Radeon R9 280 has a slightly higher core clock speed. The core clock speed (or base speed) is the frequency at which the GPU core runs. This metric makes sense when comparing GPUs of a similar architecture or generation. Despite this, the Radeon R7 M340 has a slightly higher boost clock speed: the maximum frequency the chip can reach if power delivery and thermals allow.

Furthermore, the spec sheet for both these GPUs show that the Radeon R7 M340 has slightly more memory with 4 GiB of memory compared to 3 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 R9 280 is faster than the Radeon R7 M340.
