AMD Ryzen 5 5500GT vs AMD Ryzen 5 7545U Comparison

The AMD Ryzen 5 7545U and AMD Ryzen 5 5500GT are both 6-core, 12-thread processors, but they target entirely different platforms and use different architectures. The benchmark data shows a clear overall winner in the Ryzen 5 7545U, which claims 14 of the 17 head-to-head benchmark wins, while the Ryzen 5 5500GT takes 3. Despite this, the average benchmark scores are remarkably close, with the 7545U at 26849 and the 5500GT at 26748, a difference of just 0.4%. This makes the comparison less about raw performance and more about specific workloads and platform fit.

Head-to-Head Benchmarks

The most decisive victories for the Ryzen 5 7545U come in single-threaded and lightly-threaded workloads. In Cinebench R23 single-core, the 7545U scores 2435 against the 5500GT’s 2237, an 8.9% advantage. This pattern repeats across all Cinebench versions: R15 single-core (245 vs 225, +8.9%), R20 single-core (1022 vs 939, +8.8%), and R23 multi-core (17253 vs 15848, +8.9%). The 7545U’s lead in multi-core Cinebench is consistent at roughly 8.9% across R15, R20, and R23, showing a uniform advantage in this rendering workload.

The 7545U’s biggest single-test win is in PassMark’s find prime numbers, where it scores 68 versus 54, a massive 25.9% difference. Similarly, in PassMark physics, the 7545U posts 1057 against 840, a 25.8% lead. Random string sorting also favors the 7545U heavily: 30358 vs 24583, a 23.5% margin. These results indicate the Zen 4 architecture excels at integer-heavy, latency-sensitive tasks.

The 5500GT’s wins are narrower but notable. In PassMark integer math, the 5500GT scores 64218 against 60206, a 6.2% advantage. Data compression also goes to the 5500GT: 243904 vs 238345, a 2.3% lead. Data encryption is another 5500GT win, with 14754 versus 14202, a 3.7% margin. These wins suggest the 5500GT’s higher base clock of 3.60 GHz (vs 3.20 GHz) helps in sustained throughput tasks that are not memory-bandwidth limited.

The 7545U also wins PassMark single-thread with 3673 vs 3066, a 19.8% advantage, and PassMark multithread with 20298 vs 19000, a 6.8% lead. Floating point math is nearly identical: 36754 vs 36694, a 0.2% edge for the 7545U. Extended instructions favor the 7545U at 17865 vs 17027, a 4.9% margin. In total, the 7545U wins 14 benchmarks, the 5500GT wins 3, but the overall average scores are separated by less than half a percent.

Architecture Differences

The core difference is the process node and architecture generation. The Ryzen 5 7545U uses a 4 nm TSMC process with Zen 4 architecture, codenamed Phoenix2. The Ryzen 5 5500GT uses a 7 nm TSMC process with Zen 3 architecture, codenamed Cezanne. This is a full generation gap, which explains the 7545U’s superior single-thread performance despite a lower base clock.

The 7545U packs 20,900 million transistors on a 137 mm² die, while the 5500GT has 10,700 million transistors on a 180 mm² die. The 7545U is denser and more power-efficient per transistor. Both have 6 cores and 12 threads, but the cache layout differs: the 7545U has 1 MB of L2 per core, while the 5500GT has 512 KB per core. L3 cache is 16 MB shared on both, but the 7545U’s L3 is listed as "16 MB (shared)" while the 5500GT’s is simply "16 MB".

The 7545U supports DDR5 memory with a dual-channel bus and 89.6 GB/s bandwidth, while the 5500GT supports DDR4 with 51.2 GB/s bandwidth. This is a 75% bandwidth advantage for the 7545U. The 7545U also supports ECC memory; the 5500GT does not. PCIe generations differ: the 7545U has Gen 4 with 14 lanes (CPU only), while the 5500GT has Gen 3 with 16 lanes. The integrated graphics also differ: the 7545U has Radeon 740M, while the 5500GT has Radeon Vega 7.

The 7545U is a mobile part with a 28 W TDP, while the 5500GT is a desktop part with a 65 W TDP. The 5500GT has an unlocked multiplier; the 7545U is locked. The 7545U uses AMD Socket FP7, while the 5500GT uses AMD Socket AM4. The 5500GT has a launch MSRP of $125. The 7545U was released in November 2023; the 5500GT in January 2024.

The Verdict

The data is clear for single-thread and light-thread workloads: the Ryzen 5 7545U is the superior processor. It wins every Cinebench single-core test and PassMark single-thread by margins from 8.8% to 19.8%. If your tasks are rendering in Cinebench, physics simulations, prime number calculations, or random string sorting, the 7545U is the pick. Its 25.8% lead in PassMark physics and 25.9% lead in prime number finding are decisive.

For integer math, data compression, and encryption, the Ryzen 5 5500GT is the better choice. Its 6.2% win in integer math and 3.7% win in encryption show that its higher base clock of 3.60 GHz (vs 3.20 GHz) can overcome the architectural deficit in certain sustained workloads. However, these wins are narrower than the 7545U’s victories.

The 5500GT is a desktop part with an unlocked multiplier, which means users can potentially overclock to close the gap further. It also uses the ubiquitous AM4 socket, which offers upgrade paths within that platform. The 7545U is a mobile part on the FP7 socket, which means it is typically found in laptops or mini-PCs, not traditional desktop motherboards. If you are building a desktop, the 5500GT is the only one that fits standard AM4 boards.

The 5500GT supports DDR4, which is cheaper and more widely available than DDR5. The 7545U requires DDR5 but offers 75% more memory bandwidth. The 7545U also supports ECC memory, which is a requirement for some workstation users. The 5500GT does not support ECC.

In terms of platform, if you need a mobile processor or a compact system with DDR5 and ECC support, the 7545U is the data-backed choice. If you are building a desktop on AM4 with DDR4 and want overclocking headroom, the 5500GT is the sensible pick. The overall average scores are nearly identical, so the decision hinges on socket, memory type, and specific workload priorities.

Where Each One Wins

AMD Ryzen 5 7545U: This is the winner for any task that relies on single-core speed or memory bandwidth. All Cinebench tests (R15, R20, R23) in both single and multi-core go to the 7545U by roughly 8.9%. PassMark single-thread is a 19.8% win. The 7545U crushes the 5500GT in prime number finding (+25.9%), physics (+25.8%), and random string sorting (+23.5%). This CPU is for users who prioritize responsiveness in everyday apps, light coding, or any workload that is not purely integer-math bound. The DDR5 memory support with 89.6 GB/s bandwidth makes it the choice for memory-sensitive tasks, and ECC support adds reliability for data integrity.

AMD Ryzen 5 5500GT: This CPU wins in three specific PassMark tests: integer math (+6.2%), data compression (+2.3%), and data encryption (+3.7%). These are all throughput-oriented workloads that benefit from the 5500GT’s higher base clock of 3.60 GHz. For users who do a lot of file compression, cryptographic operations, or integer-heavy calculations, the 5500GT is the better performer. The unlocked multiplier is a significant advantage for overclockers, as it allows pushing the 5500GT beyond its 4.40 GHz boost clock. The AM4 socket and DDR4 support make it a drop-in upgrade for many existing systems, which is a practical advantage not reflected in benchmark scores.
