Half L3, yes. 24 vs. 16 (available) PCIe lanes that's not half, still enough for two SSDs and a GPU, if you actually want IO buy a threadripper. The 8700G has quite a bit more baseclock, 7700 boosts higher but you can forget about that number with all-core loads. About 9 times raw iGPU TFLOPs.
Oh, those TFLOPs. 4.5 vs. my RX 5500's 5 (both in f32), yet in gaming performance mine pulls significantly ahead, must be memory bandwidth. Light inference workloads? VRAM certainly won't be an issue just add more sticks. Those TFLOPS will also kill BLAS workloads dead so scientific computing is an option.
Can't find proper numbers right now but the 7700 should have a total of about half a TFLOP CPU and half a TFLOP GPU.
So, long story short: When you're an university and a prof says "I need a desktop to run R", that's the CPU you want.
24x PCIe 5.0 vs 16x PCIe 4.0
So 8 lanes less and each lane has half the bandwith = less than half the PCIe bandwidth.
