How do the new graphics compare to vega? Is there gonna be new "vega" options in three months like last year, or are these new ones comparable to the vega?

5500m is 80W chip, unless Apple downclocks it, it should be a little slower than 1660Ti, so anywhere between 40% to double performance of Vega Pro 20 depending on task. Question is cooling, the current 15 inch maxes out at 50W sustained between CPU and GPU.
If you do any graphics work, it's a no brainer. A very modest upgrade cost.I'm still not sure if I'll take the base GPU or upgrade it..

so could we see 13 or 14 inch with dedicated GPU after all enhancement in 16 inch internals.
You can’t compare the 5500M Apple uses to the “standard” 5500M. It’s a different GPU. Apple uses the full Navi 14 chip (where the regular 5500M has two CUs disabled), most likely binned and probably with additional optimizations. It is going to be way more energy-efficient. The GPU is likely much more power efficient than what you think. Vega Pro 20 too was only 50W.
I should get mine by the end of the month and I’ll give it a test run

Not much point. The integrated GPUs have already caught up with low-end dedicated ones. Next year Intel iGPUs are supposed to get another 2x boost — and we are getting HBM3 that solves the cost issues of its predecessor.
Keep us posted please, I’ll waiting to decidé which I go with
I will only be able to test the 5500M unfortunately, so I don't know how much help it will be. Also, it will still take two weeks that I get it. But I promise to write up a report here
I might just go for it so I can play World of Warcraft on holidays without an issue lol

Let me put it like this: I think that 2 more cores, 5500M and 512 extra GB of SSD are a fantastic upgrade for $400. So if you are eyeing the 16" anyway...
From Anand:
A much more significant change, however, is on the GPU side of matters. The new laptops continue to use discrete mobile GPUs, and for their new laptop Apple is tapping AMD’s newest Radeon Pro 5300M and Radeon Pro 5500M mobile GPUs. These are based on AMD’s 7nm RDNA architecture, offering significant gains in performance and power efficiency over the Radeon Pro 500 (Polaris) chips that they replace.
As these are Apple-specific SKUs, AMD doesn’t offer a whole lot of details about the new chips, but the specifications are similar to AMD’s Radeon RX 5500M, which was announced last month. Notably, Apple’s Radeon Pro 5500M SKU has 2 more active CUs than the open market Radeon RX 5500M, however overall throughput is lower, as Apple surely running their SKUs at lower TDPs. Joining this is also the Radeon Pro 5300M, which is the base SKU for the new MacBook Pro. On paper, this chip offers around 20% performance than the 5500M. Meanwhile Apple is also segmenting their GPU options by VRAM; while the 5300M comes with just 4GB of GDDR6 memory, the 5500M comes with a rather unique to Apple 8GB of VRAM.

Overall, Apple is claiming that the new GPUs offer a significant improvement in performance over Apple’s previous generation 15-inch laptop. The Radeon Pro 5300M should be 120% faster than the Radeon Pro 555X used in the last-generation base models, while the Radeon Pro 5500M is said to offer 80% more performance than the outgoing Radeon Pro 560X.
You're right, the Pro is downclocked with 24 CU. Some sites are claiming 50W TDP - if that's true I doubt Apple's claim of 80% increase short of some single specific benchmark. Let us know when you get yours, I checked the trade-in value and it came to $1500 for my 2.2/32/2TB 2018 config, I'm not in a rush to get it. The new one maxed out with 64GB and 8TB SSD for $6k is actually not that bad, my Blade 15 with 64GB/9.8TB /RTX2060 was like $3.5k total - but that's 6 core and no battery life to speak of.You can’t compare the 5500M Apple uses to the “standard” 5500M.

Totally agree, this time I'm not going to be the first one to get it. There are some leaked ones, Time Spy looks like garbage, most likely drivers, two geekbench opencl scores, one 30k (garbage like the time spy) the other 103k - more realistic.We need benchmarks to see if the 5500M is a benefit or not
