AMD embarrasses Intel with Ryzen 7 HP ProBook 455 G7 running 150 percent faster than the more expensive Core i7 ProBook 450 G7

The latest 15.6-inch HP ProBook this year is the ProBook 450 G7 and ProBook 455 G7 powered by Intel 10th gen Comet Lake-U and AMD 3rd gen Zen 2 processors, respectively. The two models are otherwise visually identical leaving it up to buyers to decide if they want an Intel laptop or AMD laptop. Historically, the AMD model would run slower than Intel and cost less in the process, but the latest Ryzen processors have now enabled the AMD model to be both faster and cheaper.

We recently had a chance to review the ProBook 450 G7 and ProBook 455 G7 configured with the Core i7-10510U and Ryzen 7 4700U, respectively, but the performance data as shown below skews heavily in favor of the latter especially in terms of multi-thread performance. CineBench results for the Ryzen 7 4700U are 118 to 147 percent faster than the Core i7-10510U even after adjusting for performance throttling despite both processors having the same number of simultaneous threads. We made sure to run both laptops on High Performance mode as well to get the fastest results possible from each.

The story remains similar when looking at their integrated GPUs where 3DMark results are about 2x faster across the board in favor of the RX Vega 7. The gap would have likely been even wider had our AMD ProBook been configured with dual-channel RAM instead of single-channel RAM, but the numbers are impressive nonetheless.

To add salt to the wound, other aspects outside of performance like battery life and temperatures are not any shorter or warmer, respectively, on the AMD ProBook 455 G7. We're able to record a WLAN runtime of about 7 hours on each laptop with CPU temperatures of around 84 C and 67 C on the Intel and AMD, respectively, when fully stressed.

These AMD advantages aren't exclusive between the HP ProBook 450 G7 and ProBook 455 G7. We've been seeing similar results between Intel and AMD Lenovo ThinkPad laptops as well. It won't be until Intel's Tiger Lake CPUs become available before the blue chipmaker can begin closing the performance gap in the Ultrabook space.
