AMD Ryzen 7 7736U vs AMD Ryzen 7 PRO 5755GE Comparison

Where Each One Wins

The head-to-head data splits almost evenly: the AMD Ryzen 7 7736W wins 7 of the 15 shared benchmark categories, while the AMD Ryzen 7 PRO 5755GE wins 8. That near parity obscures a deeper split between sustained multi-core workloads and short-burst or memory-sensitive tasks. The 7736W takes the Cinebench R15 multi-core test with 2019 against 1789, a 12.9% lead, yet the PRO 5755GE counters with a dominant Cinebench R23 multi-core score of 17759 versus 12768, a 28.1% swing. This suggests the 5755GE thrives under extended, all-core rendering loads, while the 7736W holds an edge in older, shorter render tests.

The 7736W also wins PassMark physics by a wide margin, 1007 to 841 (19.7% ahead), plus data compression (274440 vs 252937, 8.5% ahead) and extended instructions (19384 vs 17029, 13.8% ahead). Prime number finding goes to the 7736W at 56 versus 50, a 12% lead. The 5755GE, however, takes integer math (84004 vs 78821, 6.2% ahead), floating-point math (46589 vs 44499, 4.5% ahead), and data encryption (16937 vs 15635, 7.7% ahead). Single-thread performance is effectively a tie: the 5755GE posts 3353 versus 3350 in PassMark single-thread, a 0.1% difference.

For real-world use, the 7736W looks better suited to memory-bandwidth-heavy or latency-sensitive tasks, given its compression and physics wins. The 5755GE leans toward raw ALU/FLOPS throughput, as its math and encryption results show. The data implies a mobile chip that can punch above its class in short bursts versus a desktop chip that grinds through longer compute with higher sustained power.

Architecture Differences

These two processors come from adjacent but distinct Zen generations. The AMD Ryzen 7 7736W uses Zen 3+ under the Rembrandt-R codename, built on a 6 nm process at TSMC. The AMD Ryzen 7 PRO 5755GE uses Zen 3 under Cezanne, on a 7 nm process, also at TSMC. Both have 8 cores and 16 threads, but the node shrink gives the 7736W a smaller transistor footprint, though the die size is larger at 208 mm² versus 180 mm² for the 5755GE. The 5755GE lists 10,700 million transistors; the 7736W does not have a recorded transistor count.

Cache layouts are identical in structure: 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. The 7736W lists its L3 as "16 MB (shared)" while the 5755GE simply lists "16 MB," but the usable capacity is the same. The memory controllers differ sharply: the 7736W supports DDR5 with dual-channel memory and a bandwidth of 76.8 GB/s, while the 5755GE uses DDR4, also dual-channel, but at 51.2 GB/s. That 33% bandwidth gap in favor of the 7736W explains its compression and physics wins. ECC memory is supported on the 7736W but not on the 5755GE.

PCIe generations also diverge: the 7736W offers Gen 4 with 20 lanes (CPU only), while the 5755GE sticks with Gen 3 and 16 lanes. Integrated graphics differ as well: the 7736W carries a Radeon 680M, the 5755GE a Radeon Vega 8. Sockets are incompatible: the 7736W uses AMD Socket FP7 (mobile), the 5755GE uses AMD Socket AM4 (desktop). The 7736W has a 15 W TDP, the 5755GE a 35 W TDP. The 7736W boosts to 4.70 GHz from a 2.70 GHz base; the 5755GE boosts to 4.60 GHz from a 3.20 GHz base.

Market segments reinforce the architectural intent: the 7736W is a mobile part, the 5755GE a desktop part. The 7736W released in January 2023, the 5755GE in September 2024. Neither has a recorded launch MSRP. Both are active in production and both are locked (multiplier unlocked: false).

Cache, core count, and thread count are identical: 8 cores, 16 threads, 64 KB L1 per core, 512 KB L2 per core, 16 MB shared L3. Both are locked, both are from AMD, both are active products.

Head-to-Head Benchmarks

The biggest win for the AMD Ryzen 7 PRO 5755GE is Cinebench R23 single-core, where it scores 2507 versus 1548, a 38.3% lead. That is a massive single-thread gap, far larger than the 0.1% PassMark single-thread difference suggests. The same test in multi-core shows a 28.1% lead for the 5755GE (17759 vs 12768). These two results dominate the 5755GE's case for raw performance per core or per clock.

The 7736W's largest win is PassMark physics at 19.7% (1007 vs 841). That is followed by extended instructions at 13.8% (19384 vs 17029) and Cinebench R15 multi-core at 12.9% (2019 vs 1789). The 7736W also leads in prime number finding by 12% (56 vs 50), data compression by 8.5% (274440 vs 252937), and PassMark multi-thread by 4.1% (21725 vs 20870). Random string sorting goes to the 7736W by 2.9% (28172 vs 27373).

The 5755GE's other wins are narrower: data encryption by 7.7% (16937 vs 15635), integer math by 6.2% (84004 vs 78821), and floating-point math by 4.5% (46589 vs 44499). The single-thread PassMark tests are essentially draws, with the 5755GE ahead by 0.1% (3353 vs 3350).

Notably, the Cinebench R15 and R23 multi-core results contradict each other. In R15, the 7736W leads by 12.9%, but in R23, the 5755GE leads by 28.1%. This divergence likely reflects workload duration and memory bandwidth sensitivity. The R15 test is shorter and may benefit from the 7736W's higher boost clock and DDR5 bandwidth, while R23's longer run lets the 5755GE's higher base clock (3.20 GHz vs 2.70 GHz) and 35 W TDP sustain better throughput.

The Verdict

The data points to a clear split by platform and workload. The AMD Ryzen 7 7736W is the choice for mobile systems where 15 W TDP, DDR5 memory, and PCIe Gen 4 matter. It wins memory-sensitive tasks like compression and physics, and it holds a surprising lead in Cinebench R15 multi-core. Its lower base clock (2.70 GHz) is compensated by a higher boost (4.70 GHz) and faster memory bandwidth (76.8 GB/s vs 51.2 GB/s). For users who need ECC memory support or prefer the Radeon 680M integrated graphics, the 7736W is the only option here.

The AMD Ryzen 7 PRO 5755GE suits desktop builds on AM4 with DDR4. It wins the longer, more demanding render tests (Cinebench R23) by a wide margin (28.1% multi-core, 38.3% single-core). It also takes math-heavy workloads: integer, floating-point, and encryption. Its higher base clock (3.20 GHz) and 35 W TDP allow sustained performance that the 15 W mobile chip cannot match over time. The trade-off is older memory technology (DDR4 at 51.2 GB/s) and no ECC support.

The overall average benchmark scores favor the 7736W slightly: 30364 versus 29656, a 2.4% difference. The 7736W sits at the 81st percentile of all CPUs, as does the 5755GE. The 7736W's nearest rivals include the AMD Ryzen 5 7640HS (0.1% faster average) and the Intel Core i9-11980HK (0.2% faster), while the 5755GE's nearest rivals include the AMD Ryzen 5 9600X (0.2% faster) and the AMD Ryzen 7 7840H (0.7% faster). Both chips occupy similar performance tiers despite their architectural and platform differences.

Choose the 7736W for a compact, power-efficient mobile system with modern memory and PCIe. Choose the 5755GE for a desktop that prioritizes sustained multi-core rendering and math throughput, and that can accept DDR4 and AM4. The data does not declare a single winner; it describes two tools for different jobs.
