With various end of year sales going on I started discussing 7000 series model numbering with AMD staff. Here's a handy guide we pieced together!

Mobile SKU 7ABC#:

  • A=3,4: Ryzen 3 (4 core)
  • A=5,6: Ryzen 5 (6 core)
  • A=7: Ryzen 7 (8 core)
  • A=8: Ryzen 7 if C=0, Ryzen 9 if C=5 (8 or 12 core)
  • A=9: Ryzen 9 (8 or 16 core)
  • B=2: Mendocino (Zen2)
  • BC=30: Barcelo-R (Zen3)
  • BC=35: Rembrandt-R (Zen3)
  • BC=40: Phoenix (and 7545U) (Zen4)
  • BC=45: Dragon Range (except 7545U) (Zen4)
  • #=U: < 25W
  • #=HS: 25-54W
  • #=HX: 55+W

All chips except Dragon Range are monolithic and will never have more than 8 cores. Dragon Range is chiplet ("desktop Ryzen on mobile" as an employee put it):

  • 745HX is 1 full CCD (8 cores)
  • 845HX is 2 CCDs with 2 cores disabled (12 total)
  • 945HX is 2 full CCDs (16 cores)

Think of it like 7700, 7900, and 7950 on desktop. In the same vein, 7945HX3D is like desktop 7950X3D (1 cache CCD + 1 normal)

iGPUs:

Where multiple are listed they mean Ryzen 9/7/5 respectively (Ryzen 3 has same iGPU as Ryzen 5). 600 = RDNA2, 700=RDNA3.

  • Mendocino: 610M 2CU iGPU
  • Barcelo-R: Vega GCN5
  • Rembrandt-R: 680/660/640 (12 CU, 6 CU, 4 CU)
  • Phoenix: 780/760/740 (12, 8, 4 CU)
  • Dragon Range: 610M 2CU iGPU

So for example, 7840HS = Ryzen 7, Phoenix, 25-54W. It'll be 8 core and iGPU will be 12CUs of RDNA3.

It's nice that you made this, but the formatting leaves a lot to desire. This chart wont break down specific codenames and IGP info, but it's far easier to read quickly.

Very clear and good summary on your part.

But we can all agree that this is one of the dumbest naming schemes in a while, at least since the GTX 16-series, right?

Laptop SKUs in general are stupid as hell, not helped by shit like NVIDIA deciding to do away with Max-Q/Max-P and thus make one have to do even more research about the capabilities of a laptop GPU that might not even be the same as its desktop counterpart ie the "laptop 4090 GPU"

Thanks for the effort. I'd rewrite the list like this:

Mobile SKU 7TFA#:

FA (family):

  • FA=20: Mendocino (Zen2, RDNA2)
  • FA=30: Barcelo-R (Zen3, Vega)
  • FA=35: Rembrandt-R (Zen3, RDNA2)
  • FA=40: Phoenix (and 7545U) (Zen4, RDNA3)
  • FA=45: Dragon Range (except 7545U) (Zen4, RDNA2)

T (tier):

  • T=3: Ryzen 3 (4 core)
  • T=4: Ryzen 3 (4 core Phoenix)
  • T=5: Ryzen 5 (4 core Mendocino, 6 cores otherwise)
  • T=6: Ryzen 5 (6 core Phoenix or Dragon Range)
  • T=7: Ryzen 7 (8 core)
  • T=8: Ryzen 7 (8 core Phoenix, 12 core Dragon Range)
  • T=9: Ryzen 9 (8 core Phoenix, 16 core Dragon Range)
