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.
