AMD Ryzen 5 Pro 4650U offers a good performance incentive over the Ryzen 5 4500U, the latter being leaps and bounds ahead of Intel Ice Lake-U in Cinebench R15
Laptops powered by AMD Renoir Ryzen 4000 APUs are not too far from release, and we have been seeing several benchmarks featuring the new APUs leak over the past few weeks. AMD offers a Pro-version of the APUs for business customers, which we have seen in the likes of the Lenovo ThinkPad T14 and 15 that were recently announced. A comparative benchmark between the Ryzen 5 4500U and the Ryzen 5 Pro 4650U has now emerged showing the kind of performance difference that can be expected between them.
Recent leaks have indicated the Ryzen 5 Pro 4650U to have a 2.1 GHz base and 4 GHz boost. The Ryzen 5 Pro 4650U looks to be clocked at a 200 MHz lower base frequency and features SMT, which the Ryzen 5 4500U lacks. Both SKUs feature an integrated Vega 6 iGPU.
In the 3DMark Time Spy result discovered by @_rogame on Twitter, we see that both processors have managed a similar show. The Ryzen 5 Pro 4650U, however, does seem to have an edge (~36%) over the non-Pro 4500U, especially when it comes to the CPU score, which is understandable considering the better multi-threading abilities of the Pro chip.
That being said, the overall cumulative difference between the two SKUs in this 3DMark Time Spy test is just about 1.8%. A point to be noted here is that Time Spy does not scale well above 10 threads so this may not be the most ideal benchmark for comparison.
In another leak, we get to see the Ryzen 5 4500U flex its muscles in Cinebench R15. The Ryzen 5 4500U managed to score 960 points in the test, which trumps any Ice Lake-U CPU out there, thanks to its core count advantage. For perspective, the Core i7-1065G7 scores about 706 points in the same test. Laptops powered by the Core i7-1068G7 are yet to be available, but even that CPU is likely to score lesser than the Ryzen 5 4500U.
