AMD Jaguar (2013) supports x86-64-v2.
- x86-64 level
- x86-64-v2
- Vendor
- AMD
- First products
- 2013
- Products
- A4, A6, E1 and E2 APUs (Kabini, Temash); the semi-custom APU of the PlayStation 4
- Segments
- GCC target
-march=btver2- Optimization
- Optimizing code for Jaguar and Puma
Has AVX, F16C and MOVBE but not AVX2, FMA or BMI2, so it stops at x86-64-v2.
Product lines
| Product line | Segment | Socket | Source |
|---|---|---|---|
| A-Series and E-Series (Kabini) | mobile | FT3 (BGA) | ir.amd.com |
| A-Series (Temash) | mobile | FT3 (BGA) | ir.amd.com |
| Athlon and Sempron (AM1) | desktop | AM1 | ir.amd.com |
| Opteron X-Series (Kyoto) | server | FT3 (BGA) | ir.amd.com |
| G-Series SOC | embedded | FT3 (BGA) | ir.amd.com |

Why not x86-64-v3?
Jaguar lacks AVX2, BMI2 and FMA, all of which x86-64-v3 requires.
