AMD PRO A10-8770 vs AMD Ryzen 5 2500U Comparison

The AMD Ryzen 5 2500U and the AMD PRO A10-8770 represent two very different approaches from the same manufacturer. The 2500U is a mobile processor built on the modern Zen architecture, while the PRO A10-8770 is a desktop part using the older Excavator design. Their recorded benchmark scores place them within the same performance percentile overall, yet their individual strengths and architectural foundations diverge sharply. This analysis examines the raw data, the architectural differences, and the specific conditions under which each processor holds an advantage.

FAQ

Q: Which processor has a higher average benchmark score?

A: The AMD Ryzen 5 2500U has an average benchmark score of 1058, while the AMD PRO A10-8770 scores 1046. The difference is minimal, roughly 1%, and both sit at the 29th percentile when compared against all CPUs in the database.

Q: How do their core and thread counts differ?

A: Both processors have 4 physical cores. The Ryzen 5 2500U supports 8 threads through simultaneous multithreading, whereas the PRO A10-8770 has 4 threads, meaning it does not support multithreading.

Q: What is the difference in thermal design power between the two?

A: The Ryzen 5 2500U has a TDP of 15 watts, typical for a mobile processor. The PRO A10-8770 has a TDP of 65 watts, reflecting its desktop-oriented design.

Q: Which processor has a higher base clock speed?

A: The PRO A10-8770 operates at a base clock of 3.50 GHz, which is significantly higher than the 2500U's base clock of 2.00 GHz. However, the 2500U's boost clock of 3.60 GHz is closer to the PRO A10-8770's boost of 3.80 GHz.

Q: Are their integrated graphics solutions the same?

A: No. The Ryzen 5 2500U integrates Radeon Vega 8 graphics, while the PRO A10-8770 integrates Radeon R7 graphics. Both support DDR4 memory in a dual-channel configuration.

Q: What is the release date for each processor?

A: The Ryzen 5 2500U was released on 2017-10-25. The PRO A10-8770 has no recorded release date in the database.

Where Each One Wins

The recorded head-to-head benchmark shows only one test result, but it is decisive. In the Cinebench R15 multi-core test, the Ryzen 5 2500U scores 609 points, while the PRO A10-8770 scores 306 points. That represents a 99% advantage for the 2500U, a substantial margin that reflects the impact of its newer architecture and its ability to process eight threads simultaneously.

Looking at the broader benchmark data, the Ryzen 5 2500U wins in every recorded category where a direct comparison exists. For the Cinebench R15 multi-core test, the 2500U is the clear victor. For other tests, the two chips do not share identical workloads, but the 2500U's results in Geekbench multi-core (2635) and single-core (851) suggest a consistent advantage in both parallel and single-threaded tasks. The PRO A10-8770's best results come from Cinebench R23, where it scores 3040 in multi-core and 429 in single-core, but no R23 data exists for the 2500U, so a direct head-to-head comparison is not possible.

Where the PRO A10-8770 might be seen as having an edge is in its base clock speed and boost clock speed. Its 3.50 GHz base and 3.80 GHz boost are both higher than the 2500U's 2.00 GHz base and 3.60 GHz boost. In workloads that are not heavily threaded and that rely on raw clock speed, the PRO A10-8770 could close the gap, but the available benchmark data does not show a single test where it emerges victorious.

The Ryzen 5 2500U wins the only direct benchmark contest, and its architecture provides a clear path to superiority in multi-threaded applications. The PRO A10-8770, with its higher base clock, may have an advantage in lightly threaded legacy software, but the database records no such win.

Architecture Differences

The two processors are built on fundamentally different architectures. The Ryzen 5 2500U is based on the Zen architecture, with the codename Raven Ridge. It belongs to the 2000 series and is part of the Ryzen 5 generation. The PRO A10-8770 uses the Excavator architecture, with the codename Carrizo, and is part of the A10 generation.

The manufacturing process is a major differentiator. The 2500U is fabricated on a 14 nm process at GlobalFoundries, while the PRO A10-8770 uses a 28 nm process, also at GlobalFoundries. The smaller node allows the 2500U to pack 4,950 million transistors into a die size of 210 mm². The PRO A10-8770, despite its larger 250 mm² die, contains only 3,100 million transistors. This difference in transistor density and process technology is the root cause of the performance gap.

The cache hierarchies are completely different. The Ryzen 5 2500U offers a per-core L1 cache of 96 KB, a per-core L2 cache of 512 KB, and a shared L3 cache of 4 MB. The PRO A10-8770 has a total L1 cache of 320 KB and a total L2 cache of 2 MB, with no L3 cache at all. The presence of a shared L3 cache on the 2500U is a significant architectural advantage, especially in multi-threaded workloads where cores need to share data efficiently.

The integrated graphics also differ in architecture. The 2500U features Radeon Vega 8 graphics, while the PRO A10-8770 features Radeon R7 graphics. Both support DDR4 memory, but the 2500U's graphics are part of a newer generation and are typically more capable per watt.

The memory controllers are similar: both support DDR4 in a dual-channel configuration with a memory bandwidth of 38.4 GB/s. Neither supports ECC memory. The PCIe support is also close: the 2500U provides Gen 3 with 8 lanes (CPU only), while the PRO A10-8770 provides Gen 3 without a specific lane count listed.

The PRO A10-8770 uses a different socket (AMD Socket AM4) compared to the 2500U (AMD Socket FP5). This reflects their different market segments: the PRO A10-8770 is a desktop part, while the 2500U is a mobile part. The production status for both is listed as Active.

Head-to-Head Benchmarks

The database contains one direct head-to-head benchmark result between these two processors, and it is a decisive victory for the Ryzen 5 2500U.

In the Cinebench R15 multi-core test, the Ryzen 5 2500U scores 609 points. The AMD PRO A10-8770 scores 306 points. This is a delta of 99%, meaning the 2500U delivers nearly double the performance of the PRO A10-8770 in this heavily threaded workload. The result is not surprising given the architectural differences. The 2500U's Zen architecture with 8 threads and a shared 4 MB L3 cache is designed to handle parallel workloads efficiently. The PRO A10-8770, with only 4 threads and no L3 cache, is severely constrained in such scenarios.

Looking at the broader benchmark suite, the Ryzen 5 2500U also shows strong results in Geekbench, scoring 2635 in multi-core and 851 in single-core. The PRO A10-8770 does not have a Geekbench score in the database, but its Cinebench R23 results (3040 multi-core, 429 single-core) provide a reference point. The single-core score of 429 in R23 for the PRO A10-8770 suggests that its higher clock speeds do help in lightly threaded tasks, but the 2500U's architecture appears to compensate for its lower clock speed through better instructions per cycle.

The only recorded head-to-head is the R15 multi-core test, and the 2500U wins it by a landslide. The PRO A10-8770 has no recorded wins in any head-to-head benchmark. The data indicates that for any multi-threaded application, the Ryzen 5 2500U is the vastly superior choice. For single-threaded performance, the PRO A10-8770's higher boost clock of 3.80 GHz might give it a fighting chance, but the database does not contain a direct comparison to confirm this.

The average benchmark scores are nearly identical (1058 for the 2500U, 1046 for the PRO A10-8770), which places both processors in the same overall performance tier. However, this average masks the fact that the 2500U's performance is more balanced and modern, while the PRO A10-8770 relies on clock speed and a larger die to achieve a similar average. The benchmark results show that the Ryzen 5 2500U is the superior processor in the one test where they meet directly, and its architectural advantages suggest it would win most other modern workload comparisons as well.
