Not to everyone’s surprise, Intel did announce its much-awaited Tiger Lake mobile CPUs with their revolutionary Xe graphics, which did get a lot of appreciation worldwide and more often than not doubts in our minds, is Intel bluffing with its iGPU or is it real. In comparison with AMD’s Ryzen 7 4800U, the new Core i7-1165G7 was touted to deliver around 20-30% better performance in games.
Obviously, this had stunned everyone across the globe how such a generational leap from a sleeping giant possible? Intel did never reveal any details of the test bench or how did they attain such numbers, so taking all of this with a pinch of salt.
Now, in the meantime of all this debate, our friendly tipster @_rogame has come with an interesting thing that makes some sense to Intel’s iGPU performance.
The point that when Intel showed around 40% better gaming performance than AMD’s best Ryzen 7 4800U did really kept everyone guessing, how could even this be possible? @_rogame has dug out the fact that the TigerLake iGPU does crave on the type of RAM used for the performance, yes, its RAM, now it’s not a Ryzen CPU which depends on the type of RAM for CPU performance, but it’s for the iGPU.
Now, if you closely see the benchmark chart, you clearly see the Core i5-1135G7 in action and there are two scores of it – one with the DDR4 3200MHz RAM and the other with LPDDR4x 4266MHz RAM. Now if you see the difference in the 3DMark performance is huge, the one with DDR4 RAM gets 5246 points while the LPDDR4x one gets 5999 points. In the Fire Strike test too, the difference is noticed, the DDR4 3200MHz RAM gets only 3013 points while the LPDDR4x 4266MHz RAM gives a major bump to 4612 points.
Yes, it’s this much difference in iGPU performance, and it is evident with the variety of the benchmarks used in the chart. On paper, it’s damn ridiculous, and now imagine if an OEM uses DDR4 3200MHz RAM, and one using LPDDR4x 4266MHz RAM, the difference in the much bragged Intel Xe graphics will be huge. Using the former RAM, one can get even worse performance than a Ryzen 5 4500U, however, with the latter RAM, one can get a blazing performance like an MX350 dedicated GPU.
So, Intel should probably have used the LPDDR4x 4266MHz RAM to show its dubious superiority over AMD in almost all games. This info is significant as never RAM speeds really mattered with Intel CPUs, but now it would and it will be interesting to see what type of RAMs these OEMs use and how new Tiger Lake powered laptops perform in reality.
