We test the Snapdragon 8 Gen 2 and see significant CPU and GPU improvements

News Summary:

  • Our device comes with 16 GB of RAM and 256 GB of storage, so the Snapdragon 8 Gen 2 is a great opportunity to shine. And boy, does it light up! Note that this is an improvement between generations and if you’re still on TSMC N4 nodes, including the 8+ Gen 1 (which we did), it won’t improve much. What Qualcomm has achieved is very impressive. Before moving on to the diagrams, let me introduce the chip in more detail.

  • Qualcomm announced the Snapdragon 8 Gen 2 last month, and the first phones with it are coming out. The vivo X90 Pro+ was announced first, but we don’t have the device to test it. However, we have the iQOO 11 and spent some time testing its paces. Benchmarks for the new chip have been leaked for some time. However, I’m not sure if something fishy is going on. With iQOO 11, you have a market-ready device that is known to be up to standard.

Snapdragon 8 Gen 2 uses a combination of ARM cores. Cortex-X3 is the frontrunner and according to official data should be 25% faster than Cortex-X2 used in Gen 1 chips. This is a guideline for single-threaded performance. Then there is a mix of four medium cores. Two of them are the Cortex-A715, said to be 20% faster than the older A710 core. Gen 2 chips also have two of these A710 cores, so multithreading performance is difficult to measure.

Still, Qualcomm says the new GPU is 25% faster (and 45% more efficient) than the previous generation. If anything, Qualcomm has been conservative with its GPU claims. It’s a much bigger speed boost than the Snapdragon 8+ Gen 1. This is a slight improvement (10% faster) than the original chip from earlier this year. Plaschip’s focus was on energy efficiency. Once that is achieved, Qualcomm can focus on making things faster.

It’s based on ARM data, and Qualcomm says the CPU is 35% faster overall (compared to the original 8th Gen 1 CPU) and 40% more efficient (not tested today). The Snapdragon 8 Gen 2 will also use the new Adreno 740 GPU. Qualcomm declined to elaborate on the hardware, but there must have been big changes. What’s interesting is that the 740 runs at a lower clock speed than the 730 on the Gen 1 chips.

To get a sense of the overall improvements brought by Gen 2, we’ll start with the full system benchmark, AnTuTu. Gen 1 chips only support LPDDR5 RAM and UFS 3.1 storage, so this isn’t a complete individual comparison. However, Snapdragon 8 Gen 2 supports faster LPDDR5X DRAM and UFS 4.0 storage, and iQOO 11 takes full advantage of them.
