Twitter user _rogame discovered 3DMark FireStrike benchmark scores of a quad-core, eight-threaded Intel Tiger Lake-U laptop processor with a 2.7GHz base clock. This part has a 28W TDP and uses LPDDR4X memory. He compared it against the AMD Ryzen 9 4900HS, an eight-core, sixteen-threaded model with a 3.0GHz base clock, 4.4GHz Boost, 35W TDP and DDR4-3200 memory.
The results are quite interesting. The AMD part is obviously more powerful in the overall test as it has a lot more cores and a higher TDP, but where it gets interesting is in the graphics tests. The early results show Intel's integrated Xe graphics can outperform AMD's fastest integrated Vega graphics by 10.5 percent in FireStrike. These are not final retail numbers so perhaps Intel can squeeze out even more performance with more mature drivers.
Coming to the performance numbers, you can expect the performance of the CPU to be lower than that of AMD's Ryzen 4900HS due to the lower clock and core count which is to be expected since this comparison is being made between a 35W high-performance mobility chips versus a 15W-28W Ultra-Low Power Tiger Lake chip. The CPU tests show that the AMD Ryzen 9 4900HS is up to 64% faster than Intel's Tiger Lake-U but its the graphics score that we really need to talk about.
In the graphics tests, the Intel Tiger Lake's Xe GPU is up to 10% faster than AMD's 7nm Vega GPU. It is also up to 14% faster in the second graphics test and these are still preliminary numbers which would definitely improve with optimized drivers and improved clocks on the final variant.
Intel is getting very serious about graphics and these results mean a lot of computer users can expect a big graphics performance increase when they buy their next device. Tiger Lake is expected to be out later this year.
