AMD PRO A10-8770 vs AMD Ryzen 7 PRO 3700U Comparison

FAQ

Q: Which processor has the higher boost clock?

A: The AMD Ryzen 7 PRO 3700U boosts to 4.00 GHz, while the AMD PRO A10-8770 tops out at 3.80 GHz. The mobile chip holds a 0.20 GHz advantage in peak frequency.

Q: How do the two chips compare in multi-threaded performance?

A: In the Cinebench R15 multi-core test, the Ryzen 7 PRO 3700U scores 658 versus 306 for the PRO A10-8770, a 53.5% lead. The Ryzen chip's 8 threads (versus 4) provide a significant scaling advantage.

Q: What is the transistor count difference between the two architectures?

Q: Are both processors unlocked for overclocking?

A: No. Neither the PRO A10-8770 nor the Ryzen 7 PRO 3700U has an unlocked multiplier, so both are locked for overclocking purposes.

Q: What is the memory bandwidth capability of each chip?

A: The PRO A10-8770 supports dual-channel DDR4 with a memory bandwidth of 38.4 GB/s. The Ryzen 7 PRO 3700U also supports dual-channel DDR4, but its memory bandwidth figure is not specified in the data.

Architecture Differences

The two processors represent fundamentally different AMD design philosophies separated by several generations. The PRO A10-8770 uses the Excavator architecture with the Carrizo codename, built on a 28 nm process at GlobalFoundries. It is a desktop part with a 65 W TDP, while the Ryzen 7 PRO 3700U is a mobile chip using the Zen+ architecture with the Picasso codename, fabricated on a 12 nm node, also at GlobalFoundries. The process shrink from 28 nm to 12 nm is central to the Ryzen chip's efficiency, enabling a 15 W TDP despite more transistors.

The transistor counts tell a stark story: the PRO A10-8770 integrates 3,100 million transistors on a 250 mm² die, while the Ryzen 7 PRO 3700U crams 4,940 million transistors into a smaller 210 mm² package. That is roughly 59% more transistors in a 16% smaller area, reflecting the density improvements of the newer process node.

Cache hierarchies diverge sharply. The PRO A10-8770 has 320 KB of L1 cache and 2 MB of L2 cache, with no L3 cache. The Ryzen 7 PRO 3700U allocates 96 KB of L1 per core, 512 KB of L2 per core, and a 4 MB shared L3 cache. For a 4-core processor, this translates to 384 KB total L1 and 2 MB total L2, but the additional 4 MB L3 gives the Ryzen chip a substantial memory hierarchy advantage.

Threading is another fundamental difference. The PRO A10-8770 is a 4-core, 4-thread processor, while the Ryzen 7 PRO 3700U is a 4-core, 8-thread part with simultaneous multithreading. This doubles the logical thread count, which directly impacts multi-threaded workloads.

Both chips feature integrated graphics, but with different Radeon implementations: the PRO A10-8770 has Radeon R7 graphics, while the Ryzen 7 PRO 3700U has Radeon Vega 10. Both support dual-channel DDR4 memory and PCIe Gen 3, and neither supports ECC memory. Sockets differ completely, with the desktop A10 using AMD Socket AM4 and the mobile Ryzen using AMD Socket FP5.

Head-to-Head Benchmarks

The only direct head-to-head benchmark available is Cinebench R15 multi-core, and the result is decisive. The Ryzen 7 PRO 3700U scores 658, while the PRO A10-8770 scores 306. This represents a 53.5% advantage for the Ryzen chip, meaning the Ryzen 7 PRO 3700U delivers more than double the multi-threaded rendering performance of the PRO A10-8770.

The source of this gap is clear from the architecture differences. The Ryzen chip's 8 threads versus 4 threads provides a theoretical 100% increase in thread count, and while real-world scaling is never perfect, the 53.5% lead shows strong utilization of that extra threading capacity. The Ryzen chip also benefits from its 4 MB L3 cache, which reduces memory latency for repeated data access patterns typical in rendering workloads.

Looking at individual benchmark scores beyond the head-to-head, the Ryzen 7 PRO 3700U shows additional strengths. In Cinebench R15 single-core, it scores 149, while the PRO A10-8770 has no single-core R15 result in the data. The Ryzen chip also posts Cinebench R20 scores of 1276 multi-core and 180 single-core, plus Geekbench scores of 2567 multi-core and 790 single-core. The PRO A10-8770 has its own Cinebench R20 results of 1276 multi-core and 180 single-core, which happen to match the Ryzen chip's R20 multi-core figure exactly, though the Ryzen's single-core R20 is not listed in the head-to-head data.

The average benchmark scores are remarkably close: the PRO A10-8770 averages 1046, while the Ryzen 7 PRO 3700U averages 1041. Despite the Ryzen chip's overwhelming win in the multi-core rendering test, the overall average is nearly identical, suggesting that the PRO A10-8770 performs competitively in other workload types not covered by the head-to-head comparison. Both processors sit at the 29th percentile among all CPUs.

Nearest rival data contextualizes both chips. The PRO A10-8770's closest competitors include the Intel Core i5-6350HQ (matching 1046 average score), the AMD Athlon X4 950 (1047, 0.1% ahead), and the AMD PRO A10-9700 (1045, 0.1% behind). The Ryzen 7 PRO 3700U sits near the Intel Core i3-4160T (1043, 0.2% ahead), the Intel Core i7-4558U (1038, 0.3% behind), and the Intel Pentium Gold G5620 (1045, 0.4% ahead). Both chips land in a crowded performance band where 1% separates competitors.

The Verdict

The data clearly favors the Ryzen 7 PRO 3700U for multi-threaded workloads. Its 53.5% lead in Cinebench R15 multi-core over the PRO A10-8770 is a decisive margin, driven by double the thread count and the substantial cache advantage. Any user running rendering, video encoding, or heavily threaded productivity tasks should choose the Ryzen 7 PRO 3700U based on this benchmark evidence.

The PRO A10-8770 is not without merit, however. Its average benchmark score of 1046 slightly edges the Ryzen chip's 1041, and it matches the Ryzen 7 PRO 3700U's Cinebench R20 multi-core score exactly at 1276. For single-threaded performance, the PRO A10-8770's Cinebench R23 single-core score of 429 stands well above the Ryzen chip's R15 single-core score of 149, though these are different benchmark versions and not directly comparable.

The PRO A10-8770 offers a 65 W TDP in a desktop socket, making it suitable for always-on systems where power consumption is less critical. The Ryzen 7 PRO 3700U's 15 W TDP is a dramatic efficiency advantage, consuming less than a quarter of the power budget while delivering superior multi-threaded performance. This makes the Ryzen chip the clear choice for battery-powered or thermally constrained systems.

Neither processor supports ECC memory, and both are locked. The PRO A10-8770's AM4 socket offers desktop upgrade potential, while the Ryzen 7 PRO 3700U's FP5 socket is mobile-only. The Ryzen chip's newer 12 nm process and 4 MB L3 cache represent forward-looking design choices, while the PRO A10-8770's 28 nm Excavator architecture is older technology.

For a desktop user prioritizing raw multi-threaded performance per watt, the Ryzen 7 PRO 3700U is the data-backed winner. For a budget desktop build where single-threaded performance and slightly higher average scores matter, the PRO A10-8770 remains competitive. The overall percentile ranking is identical at 29 for both, indicating they occupy the same performance tier in the broader CPU landscape.
