Nvidia RTX 5080 laptop GPU performance leak shows 18% improvement over RTX 4080

Nvidia has officially announced the RTX 50 series GPUs for both desktops and laptops, including the RTX 5080, 5090, 5070 Ti, and more. Team Green showed off a couple of performance comparisons of the new graphics cards, but those benchmark numbers cannot be taken as is. First-party performance data is usually skewed to favor the newer products, so they aren't always reliable. Third-party and independent testing are always more accurate in such cases.

Since the new RTX 50 series laptop GPUs are under embargo and not yet available on the market, there has been no independent testing. However, a new leak has come forward, which provides more insight into the raw performance improvements the new RTX 5080 laptop graphics chip can deliver. According to this leak, the new GPU may churn out around 18% more performance compared to the RTX 4080.

Geekbench 6 OpenCL test showcases what you can expect from RTX 5080

The Nvidia RTX 5080 was recently benchmarked with Geekbench 6's OpenCL test, and its scores were uploaded to the Geekbench database. This benchmark was spotted by the X user @Benchleaks, who has a track record of providing credible info regarding such topics.

This RTX 5080 benchmark was done on an Alienware 18 Area-51 laptop, which is a well-designed machine with good thermals. The GPU scored 190,326 points in total, which puts it around 18% ahead of the Nvidia RTX 4080 laptop and 6% ahead of the 4090 laptop. As announced earlier, this 5080 has 16GB of memory, which is also mentioned in the benchmark.

That database also reports only a 1500 MHz clock speed for the GPU, which seems a bit on the lower side. This could either be an error in validating the clock speed, or it is possible that the graphics chip was underpowered at the time of testing (not unusual in pre-production machines). It's also possible that the graphics chip was running on older drivers, so there could be more performance left on the table. We should wait for more independent performance tests, to get a clearer understanding of the situation.
