AMD Ryzen 9 270 vs AMD Ryzen 9 7940H Comparison

The AMD Ryzen 9 7940H and the AMD Ryzen 9 270 are nearly identical on paper, but benchmark data reveals a clear split: the Ryzen 9 270 dominates Cinebench rendering workloads, while the Ryzen 9 7940H counters in several PassMark tests. The Ryzen 9 270 is the winner for sustained multi-threaded productivity, taking 10 of 17 head-to-head benchmarks, including a decisive 6.6% lead in Cinebench R23 multi-core. The Ryzen 9 7940H is the pick for single-threaded PassMark tasks and specific math operations, but its overall average benchmark score (40,431) is only 0.5% higher than the Ryzen 9 270’s (40,246), making the 270 the more consistent performer for most workloads.

The Verdict

The data points to the AMD Ryzen 9 270 as the superior chip for compute-heavy tasks. It wins every Cinebench test, from R15 multi-core (2,664 vs 2,490) to R23 single-core (3,732 vs 3,487), with a uniform 6.5–6.6% margin across the board. This consistency suggests a meaningful efficiency or clock behavior advantage, despite both chips sharing the same 4.00 GHz base and 5.20 GHz boost clocks. The 270 also wins PassMark multi-thread (29,089 vs 29,063) and physics (1,365 vs 1,300), reinforcing its edge in sustained parallel loads.

The Ryzen 9 7940H is not obsolete, however. It wins PassMark single-thread (3,952 vs 3,784) by 4.4%, plus integer math (101,977 vs 98,266) and floating-point math (62,057 vs 60,122). For users prioritizing those specific workloads, the 7940H is the better choice. But for the broadest performance across rendering, physics, and common productivity suites, the Ryzen 9 270 is the verdict. Its 87th percentile ranking matches the 7940H, yet it achieves that with a higher TDP of 45W versus 35W, indicating it uses more power to deliver better results.

Architecture Differences

Both processors are built on the same Zen 4 architecture, manufactured on TSMC’s 4nm process node, with identical transistor counts of 25,000 million and a die size of 178 mm². The core configuration is also identical: 8 cores and 16 threads, with 64 KB of L1 cache per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The key architectural difference lies in the codename: the 7940H is part of the Phoenix family, while the 270 is from the Hawk Point family. Both use the same AMD Socket FP8, support dual-channel DDR5 memory with 89.6 GB/s bandwidth, and feature the same Radeon 780M integrated graphics.

The notable functional difference is ECC memory support. The 7940H supports ECC memory; the Ryzen 9 270 does not. This is a critical distinction for workstation or server-like use cases where data integrity is paramount. Both chips have Gen 4 PCIe with 20 lanes (CPU only) and are locked multipliers. The 270 was released on January 5, 2025, while the 7940H has no listed release date in the data. Both have a production status of Active, and both are mobile market segments.

Head-to-Head Benchmarks

The Ryzen 9 270’s Cinebench sweep is the headline story. In Cinebench R23 multi-core, it scores 26,438 versus the 7940H’s 24,703, a 6.6% advantage. The single-core R23 result follows the same pattern: 3,732 vs 3,487, also 6.6% higher. This carries through R20 multi-core (11,103 vs 10,375) and R15 multi-core (2,664 vs 2,490). The 270’s wins are not marginal; they are consistent across every version of Cinebench, indicating a genuine performance uplift in rendering tasks.

The 7940H fights back in PassMark. Its single-thread score of 3,952 beats the 270’s 3,784 by 4.4%. In integer math, the 7940H scores 101,977 versus 98,266, a 3.8% win. Floating-point math also favors the 7940H: 62,057 vs 60,122, a 3.2% margin. Data encryption (21,096 vs 20,852) and data compression (352,077 vs 351,398) are narrow 7940H wins, while extended instructions (26,804 vs 26,729) is a 0.3% edge.

The remaining tests split closely. The 270 wins PassMark multi-thread (29,089 vs 29,063) by just 0.1%, physics (1,365 vs 1,300) by 4.8%, random string sorting (42,819 vs 42,093) by 1.7%, and find prime numbers (88 vs 81) by 8%. The 7940H takes 7 wins total, but the 270’s 10 wins include the heavier rendering benchmarks, which are often more representative of sustained CPU load.

Where Each One Wins

The AMD Ryzen 9 270 is the clear choice for content creation and rendering. Its 6.6% lead in Cinebench R23 multi-core and similar margins in R15 and R20 make it the stronger option for video encoding, 3D rendering, and any workload that scales across all 16 threads. The 270 also wins in physics simulations (4.8% ahead) and random string sorting, making it versatile for scientific and data-processing tasks. Its higher 45W TDP suggests it can sustain these boosts more readily than the 35W 7940H.

The AMD Ryzen 9 7940H is the pick for specific math-heavy tasks and single-threaded PassMark applications. Its 4.4% lead in PassMark single-thread makes it better for lightly threaded software, while integer and floating-point math wins (3.8% and 3.2%) indicate an edge in financial modeling, engineering calculations, and spreadsheet-heavy workloads. The 7940H also supports ECC memory, which the 270 lacks, giving it a niche advantage for error-sensitive workstation tasks. For users who need ECC or prioritize PassMark single-thread and math performance, the 7940H wins. For everyone else, the Ryzen 9 270’s rendering dominance and higher TDP make it the better all-round performer.
