AMD Ryzen 5 5600GT vs AMD Ryzen 5 PRO 4655GE Comparison

Head-to-Head Benchmarks

The benchmark data for these two AMD Socket AM4 processors is decisively one-sided. Across all 17 head-to-head comparisons, the AMD Ryzen 5 5600GT wins every single test. The AMD Ryzen 5 PRO 4655GE does not record a single victory. This is not a close contest; it is a consistent, across-the-board sweep.

The most striking pattern emerges in the Cinebench suite. In Cinebench R23 multicore, the 5600GT scores 17,272 against the 4655GE's 12,045, a 30.3% difference. The same margin appears in Cinebench R23 single-core (2,438 vs 1,700, also 30.3%). This consistency extends backward through older Cinebench versions: R20 multicore shows 7,254 versus 5,058 (30.3%), R20 single-core shows 1,023 versus 714 (30.2%), R15 multicore shows 1,740 versus 1,213 (30.3%), and R15 single-core shows 245 versus 171 (30.2%). The uniformity of these deltas suggests a fundamental architectural advantage rather than workload-specific quirks.

PassMark results reinforce the same narrative with slightly varying margins. The largest gap appears in the find prime numbers test, where the 5600GT scores 57 versus the 4655GE's 28 — a massive 50.9% advantage. This test is particularly sensitive to core efficiency and clock speed, and the result here is dramatic. Extended instructions show a 34.6% gap (18,041 vs 11,792), while physics simulation shows a 32.3% gap (875 vs 592). Floating-point math lands at 29.8% (39,817 vs 27,947), and integer math at 30.3% (69,566 vs 48,513).

The narrowest margins still favor the 5600GT substantially. Random string sorting shows an 18.4% advantage (26,188 vs 21,382), and single-thread performance shows a 20.5% gap (3,348 vs 2,660). Data compression is 25.4% ahead (258,882 vs 193,067), and data encryption is 27% ahead (15,873 vs 11,586). The multithread PassMark score mirrors the Cinebench pattern at 30.3% (20,325 vs 14,171).

It is notably the 4655GE's aggregate average benchmark score of 20,900 places it in the 74th percentile of all CPUs, with nearest rivals like the Intel Core Ultra 7 268V (20,897) and Intel Core i5-12600T (20,917) essentially tied. The 5600GT's average of 20,733 also sits in the 74th percentile, with rivals like the Intel Core i5-12490F (20,802) close behind. Despite the 5600GT's sweep in direct comparison, both processors occupy a similar overall performance tier when measured against the broader CPU landscape.

The Verdict

The data is unambiguous. The AMD Ryzen 5 5600GT is the superior processor in every measured benchmark. If the choice is between these two specific chips, the 5600GT is the only reasonable selection based on performance alone.

The 4655GE does have one distinguishing characteristic: a 35-watt TDP compared to the 5600GT's 65 watts. For builders prioritizing power efficiency above all else, this lower thermal envelope is a genuine advantage. However, the performance cost is severe — roughly 30% across most multi-threaded workloads, and up to 50.9% in prime number computation.

For general desktop use, content creation, or any workload that benefits from higher single-thread and multi-thread scores, the 5600GT's Zen 3 architecture and higher clock speeds deliver consistently better results. The 5600GT also offers an unlocked multiplier, enabling overclocking, whereas the 4655GE is locked. The 5600GT carries a launch MSRP of $140, which can be stated as reference.

The 4655GE retains relevance only in scenarios where its 35-watt TDP is a hard constraint — for example, in compact or passively cooled systems where thermal dissipation is limited. Even then, the performance trade-off is substantial. For any user who can accommodate the 65-watt TDP, the 5600GT is the clear winner.

Specification Differences

The two processors share several core specifications. Both have 6 cores and 12 threads, both use AMD Socket AM4, both support DDR4 memory in dual-channel configuration, both have 51.2 GB/s memory bandwidth, and both integrate Radeon Vega 7 graphics. Both are fabricated on TSMC's 7 nm process.

Key differences begin with clock speeds. The 4655GE has a base clock of 3.30 GHz and a boost clock of 4.20 GHz. The 5600GT runs at 3.60 GHz base and 4.60 GHz boost — 300 MHz and 400 MHz higher respectively.

TDP differs significantly: 35 watts for the 4655GE versus 65 watts for the 5600GT. This nearly doubles the thermal design power.

PCIe configuration also varies. The 4655GE provides Gen 3 with 20 lanes (CPU only), while the 5600GT provides Gen 3 with 16 lanes (CPU only).

ECC memory support is present on the 4655GE but absent on the 5600GT. The multiplier is unlocked on the 5600GT but locked on the 4655GE.

Release dates differ: the 4655GE launched on 2022-11-10, while the 5600GT launched on 2024-01-07. The 5600GT has a launch MSRP of $140; the 4655GE has no listed launch MSRP.

Part numbers also differ: the 4655GE uses 100-000001156100-100001156MPK, and the 5600GT uses 100-000001488.

Architecture Differences

The 4655GE belongs to the 4000 series and uses the Zen 2 architecture under the codename Renoir. The 5600GT belongs to the 5000 series and uses the Zen 3 architecture under the codename Cezanne. This architectural generational leap is the primary driver of the performance differences observed in benchmarks.

Both are 7 nm TSMC parts, but transistor counts differ. The 4655GE contains 9,800 million transistors on a 156 mm² die. The 5600GT contains 10,700 million transistors on a 180 mm² die — 900 million more transistors and 24 mm² more silicon.

Cache hierarchy differs in L3 capacity. Both have 64 KB of L1 cache per core and 512 KB of L2 cache per core. The 4655GE has 8 MB of shared L3 cache, while the 5600GT has 16 MB of L3 cache — exactly double.

Neither processor features 3D V-Cache. Both have identical memory support (DDR4, dual-channel, 51.2 GB/s bandwidth) and identical integrated graphics (Radeon Vega 7).

The Zen 3 architecture in the 5600GT delivers higher instructions per clock compared to Zen 2 in the 4655GE, which explains why the 5600GT maintains roughly a 30% lead even in tests where clock speed differences (3.60/4.60 GHz vs 3.30/4.20 GHz) would not fully account for the margin.

Where Each One Wins

The AMD Ryzen 5 5600GT wins in every performance category measured. This includes single-thread workloads (Cinebench R15/R20/R23 single-core, PassMark single-thread), multi-threaded workloads (Cinebench multicore, PassMark multithread), and specialized tasks such as data compression, data encryption, extended instructions, prime number finding, floating-point math, integer math, physics simulation, and random string sorting.

The 5600GT is the appropriate choice for users who want maximum performance in general desktop applications, content creation, software development, or any workload where higher benchmark scores translate to faster completion times. Its unlocked multiplier also makes it suitable for enthusiasts who plan to overclock.

The AMD Ryzen 5 PRO 4655GE does not win a single benchmark. Its only advantage is a lower TDP of 35 watts versus 65 watts. This makes it suitable for power-constrained builds, small form factor systems with limited cooling, or environments where energy efficiency is prioritized over raw performance. It also supports ECC memory, which may be relevant for certain workstation or server-adjacent use cases where data integrity is critical.

However, the performance gap is substantial. For the vast majority of users, the 5600GT's 30% or greater lead in most tests will outweigh the 4655GE's power efficiency advantage. The choice ultimately comes down to whether the 30-watt TDP reduction and ECC support justify sacrificing roughly 30% performance across the board. The benchmark data clearly favors the 5600GT for anyone who can accommodate its higher thermal design power.
