A: The 7520U wins all three single-core comparisons. In Cinebench R15 single-core it scores 168.8 versus 102 for the R2544, a 39.6% lead. In R23 single-core it scores 1171 versus 1018, a 13.1% lead.

The Verdict

The data points to a clear split by use case. The Ryzen 5 7520U is the better all-around performer in most measured tests. It wins three of the four head-to-head benchmarks, including both single-core tests and the Cinebench R15 multi-core test. Its 15W TDP and 6nm process make it the obvious choice for mobile and power-sensitive systems.

The Ryzen Embedded R2544 is the pick when you need embedded features. It supports ECC memory, offers 16 PCIe Gen 3 lanes, and uses a desktop socket (FP5) aimed at embedded designs. Its 45W TDP and 12nm process are less efficient, but the R2544 dominates in Cinebench R23 multi-core with a 40.1% lead, which suggests it sustains heavy multi-threaded loads better.

If you are building a compact, power-efficient laptop or thin client, the 7520U is the right call. If you need a rugged embedded board with ECC and PCIe expansion, the R2544 is the one.

Head-to-Head Benchmarks

The four head-to-head tests show a lopsided scorecard: the 7520U takes three wins, the R2544 takes one.

The biggest margin belongs to the R2544 in Cinebench R23 multi-core. It scores 7213 against 5149 for the 7520U, a 40.1% advantage. This is a substantial gap and indicates the R2544 can sustain heavy all-core workloads despite its older architecture. The 45W TDP likely plays a role here, as the R2544 has more thermal headroom to keep all four cores at high clocks.

The 7520U's largest win is in Cinebench R15 single-core. It scores 168.8 versus 102 for the R2544, a 39.6% lead. That is a massive single-core advantage and reflects the newer Zen 2 architecture and the 4.30 GHz boost clock.

In Cinebench R15 multi-core, the 7520U scores 834 versus 726 for the R2544, a 12.9% lead. This is a moderate win for the 7520U, showing that even in multi-threaded work the newer architecture and higher boost help.

In Cinebench R23 single-core, the 7520U scores 1171 versus 1018 for the R2544, a 13.1% lead. Again, the 7520U's higher boost clock and Zen 2 cores carry the day.

The average benchmark scores tell a similar story. The R2544 averages 2086 across all recorded benchmarks, while the 7520U averages 2046. The R2544 sits at the 46th percentile of all CPUs, the 7520U at the 45th. These are nearly identical overall positions, which makes the head-to-head deltas more interesting: the two chips trade blows depending on the workload.

Specification Differences

The two CPUs differ in nearly every specification except core count, thread count, L2 cache, and L3 cache. Both have 4 cores, 8 threads, 512 KB of L2 per core, and 4 MB of shared L3.

Clock speeds differ significantly. The R2544 has a base clock of 3.35 GHz and a boost clock of 3.70 GHz. The 7520U has a base clock of 2.80 GHz and a boost clock of 4.30 GHz. The 7520U boosts much higher but starts from a lower base clock.

TDP is a major differentiator. The R2544 draws 45W, while the 7520U draws only 15W.

The sockets are different: the R2544 uses AMD Socket FP5, the 7520U uses AMD Socket FT6. They are not interchangeable.

Memory support differs. The R2544 uses DDR4 with dual-channel support and 51.2 GB/s of bandwidth. The 7520U uses LPDDR5 with dual-channel support and 88.0 GB/s of bandwidth.

Architecture Differences

The R2544 is built on Zen+ architecture with the Picasso codename, fabricated on a 12nm process at GlobalFoundries. The die measures 210 mm² and contains 4,940 million transistors. The 7520U uses Zen 2 architecture with the Mendocino codename, fabricated on a 6nm process at TSMC. Its die measures 100 mm²; transistor count is not recorded in the database.

The process node difference is significant: 12nm versus 6nm. The 7520U's smaller node allows for a much smaller die (100 mm² versus 210 mm²) and a much lower TDP (15W versus 45W) while still delivering higher boost clocks.

Cache layouts differ in L1. The R2544 has 96 KB of L1 per core, while the 7520U has 64 KB of L1 per core. L2 and L3 are identical: 512 KB per core and 4 MB shared, respectively.

The R2544 supports ECC memory, a feature absent on the 7520U. This is an architectural choice tied to the embedded market segment.

Memory architecture differs. The R2544 uses DDR4 with 51.2 GB/s bandwidth. The 7520U uses LPDDR5 with 88.0 GB/s bandwidth. The 7520U's memory controller is designed for low-power mobile memory, while the R2544's is designed for standard desktop DIMMs.

PCIe implementation differs. The R2544 has 16 Gen 3 lanes, the 7520U has 4 Gen 3 lanes. This reflects the R2544's embedded role, where expansion cards and peripherals are common.

Where Each One Wins

The Ryzen 5 7520U wins in single-threaded performance across the board. It leads by 39.6% in Cinebench R15 single-core and by 13.1% in Cinebench R23 single-core. It also wins Cinebench R15 multi-core by 12.9%. The 7520U is the better choice for everyday responsive computing, light productivity, and any workload that relies on high boost clocks.

The Ryzen Embedded R2544 wins in Cinebench R23 multi-core by 40.1%. This is a large margin and suggests the R2544 is better at sustained all-core workloads, likely due to its higher TDP and thermal headroom. The R2544 also wins on features: ECC memory support, 16 PCIe Gen 3 lanes, and a desktop socket make it the right pick for embedded systems, industrial PCs, and server-adjacent applications.

The 7520U is the pick for mobile devices, thin clients, and power-constrained builds. Its 15W TDP and 6nm process make it far more efficient. The R2544 is the pick for systems that need reliability features like ECC and expansion capability, even at the cost of power efficiency.

In terms of overall benchmark position, the two chips are nearly identical. The R2544 sits at the 46th percentile of all CPUs with an average score of 2086. The 7520U sits at the 45th percentile with an average score of 2046. The R2544 is 0.2% ahead of the Intel Core i3-9350KF and 0.4% behind the AMD Ryzen 7 1700X. The 7520U is 0.1% behind the Intel Xeon E3-1270 v5 and 0.4% ahead of the Intel Core i7-7700T. Both chips are firmly in the mid-range of the database.
