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.
Thanks for the effort. I’d rewrite the list like this:
Mobile SKU 7TFA#:
FA (family):
T (tier):
