I'm interested to see the benchmarks vs. comparable AMD systems. Some of the claims, like 2x performance increase on the MBP are impressive, but intel laptops have been absolutely trounced by AMD 4000-series laptops of late.
Also will be interested to see the benchmarks of the integrated GPU vs. discreet GPU performance.

If they're "only" claiming 2x over anyone else' integrated, then it's not going to be all that interesting to compare integrated vs. discreet. By comparison here the 2060 Max Q is around 4x faster than the Vega 8 in the 4800U. Although that 2x faster than anyone else's integrated also has some really big question marks on the claim. The fine-print on that claim includes: "Integrated GPU is defined as a GPU located on a monolithic silicon die along with a CPU and memory controller, behind a unified memory subsystem" Which sounds a bit weasel-y like it's trying to specifically exclude what's commonly thought of as integrated graphics like the two-die approach in Tigerlake. Which how the product is packaged shouldn't really matter?
- skohan 6y agoThe claim was 2x CPU performance over the previous 13" MBP, and 5-6x GPU performance over the previous integrated graphics.
- kllrnohj 6y agohttps://www.apple.com/mac/m1/ https://www.apple.com/mac/m1/ There's no claim of any 5-6x faster than previous there. It says "fastest integrated" (and in the fine print that integrated is specifically unified monolithic die, eliminating chiplet-style products), and then also "M1 delivers significantly higher graphics performance than the very latest PC laptop chip — for up to 2x the graphics speed." So take the 4800U, which has among the fastest commercially available integrated graphics in a monolithic die, and double the GPU performance. If you needed a discreet GPU in your laptop previously this probably won't change that.
- CraftThatBlock 6y agoI don't think they included Intel's new Xe or AMD's APU in those 2x for iGPUs.
- vbezhenar 6y agoThey claim 2 TFlops for their GPU. RTX 3090 features 143 TFlops.
- skohan 6y agoWhat would be a comparable card at 2 TFlops?
- vbezhenar 6y agoActually I'm not sure that my number is correct, so I better won't spread misinformation. It's not clear what those Apple flops really mean and there are multiple characteristics for modern GPUs which are measured in flops with different values: half precision, single precision, double precision, tensor compute, sparse tensor compute.
