Q: Do both CPUs have the same overall average score?

A: No. The 6950HS has an average benchmark score of 31850, while the 8945HS has 31074, but these figures come from different benchmark suites and are not directly comparable. The head-to-head tests, which use identical workloads, all favor the 8945HS.

Q: Which CPU has a higher TDP?

A: The 8945HS has a TDP of 45 W, while the 6950HS is rated at 35 W. This makes the 6950HS a lower-power option, but the benchmark data shows no performance benefit from that lower power draw.

Architecture Differences

Both CPUs have 8 cores and 16 threads, but they belong to different architectural generations. The 6950HS is based on Zen 3+ (Rembrandt) on a 6 nm process, while the 8945HS uses Zen 4 (Hawk Point) on a 4 nm process. The die size shrinks from 208 mm² to 178 mm², and the 8945HS integrates 25,000 million transistors. The L2 cache per core doubles from 512 KB to 1 MB, while L3 remains 16 MB shared. Base clock rises from 3.30 GHz to 4.00 GHz, and boost from 4.90 GHz to 5.20 GHz. The 8945HS also has a higher TDP (45 W vs 35 W) and a newer socket (FP8 vs FP7). Memory bandwidth increases from 76.8 GB/s to 89.6 GB/s. The integrated GPU moves from Radeon 680M to Radeon 780M. Both support DDR5 dual-channel, PCIe Gen 4 with 20 lanes, and lack ECC. Neither has an unlocked multiplier. The 8945HS also has a later release date, 2023-12-05 versus 2022-04-18 for the 6950HS.

Head-to-Head Benchmarks

The head-to-head data covers 17 tests, and the 8945HS wins every single one. The largest margin is in PassMark's find prime numbers, where the 8945HS scores 92 versus 56, a 39.1% lead. In Cinebench R23 multi-core, the 8945HS scores 16795 against 11515, a 31.4% advantage. Random string sorting shows a 32.1% gap (43202 vs 29350). Extended instructions are 29.9% higher (26964 vs 18897). Geekbench multi-core is 28.7% higher (12276 vs 8756). Cinebench R15 multi-core is 27.5% higher (2640 vs 1913). PassMark physics is 27.3% higher (1434 vs 1043). PassMark multithread is 23.5% higher (29780 vs 22775). Floating point math is 22.2% higher (61821 vs 48096). Data compression is 20.7% higher (356508 vs 282624). Data encryption is 16.3% higher (21323 vs 17837). Single-core tests also favor the 8945HS: Cinebench R23 single-core is 16.1% higher (1805 vs 1514), R15 single-core is 14.9% higher (281 vs 239), PassMark single-thread is 11.7% higher (3850 vs 3400), and Geekbench single-core is 10.1% higher (2116 vs 1903). Integer math shows a 12.9% lead (101226 vs 88124). The smallest margin is in Geekbench single-core at 10.1%, but it is still a clear win.

The 8945HS also has additional 3DMark results not present for the 6950HS, including 16-thread, 2-thread, 4-thread, 8-thread, max-thread, and single-thread scores. These are not part of the head-to-head comparison but indicate the 8945HS has a broader benchmark profile. The 6950HS, by contrast, has no 3DMark entries in the database.

The Verdict

The data is unambiguous: the AMD Ryzen 9 8945HS outperforms the Ryzen 9 PRO 6950HS in every recorded head-to-head test. For users who prioritize raw performance in multi-threaded workloads, rendering, or number crunching, the 8945HS is the clear choice. Its higher boost clock, larger L2 cache, and newer Zen 4 architecture deliver substantial gains across the board. The 6950HS, however, has a lower TDP of 35 W versus 45 W, which may be relevant for systems where power draw and thermal output are constrained. But the benchmark results show no scenario where the 6950HS wins. The 8945HS also offers a more capable integrated GPU (Radeon 780M vs 680M) and higher memory bandwidth. Given that both CPUs are active and mobile, the 8945HS is the superior performer. The 6950HS remains a viable option only if the lower TDP is a hard requirement, but the performance gap is significant.
