Intel Core i5-11300H vs Core i5-1135G7 – the newer CPU seems like a faster chip

The Intel Core i5-11300H and Core i5-1135G7 are two “blue” CPUs that are equally priced at $309.00 (bulk price for 1000 units). Both CPUs are based on the Tiger Lake tech but the H variant belongs to the H35 series while the Core i5-1135G7 is a UP3 unit.

At least on paper, both siblings are close – they have equal core and thread count – 4 cores and 8 threads, the cache size is the same (8MB), and in terms of memory supported frequencies they are on the same boat – DDR4-3200, LPDDR4x-4267.

However, the Core i5-11300H has a bigger TDP and as an H CPU, it may have more tricks under its sleeve. So, let’s check the performance of these two rivals.

CPU benchmarks

Expectedly, the Core i5-11300H is faster compared to the Core i5-1135G7 in 3D Rendering. It looks like in these situations the bigger TDP has the final word.

GPU benchmarks

Both CPUs are equipped with the same iGPU – Intel Iris Xe Graphics G7 (80EU). Now, in this scenario, the iGPU performance can vary from configuration to configuration and it depends on the memory clock, the single-channel RAM has a negative impact on the iGPU results while the dual-channel memory definitely helps in every situation. So, at least for now, we have results from a prototype laptop and we prefer to test the final version of the product before making any conclusions when it comes to the iGPU “department”.


So, both processors are equally priced ($309.00) and they have the same core count, cache size, and memory-supported frequencies. At least for now the Core i5-11300H has the upper hand when it comes to pure CPU computational performance. On the other hand, the H CPU dissipates more heat and if you need a thinner laptop maybe the Core i5-1135G7 is a better solution.
