AMD A10-7700K vs AMD PRO A10-8750B Comparison

The Verdict

The data shows two closely matched AMD desktop processors from the same Steamroller family, but the AMD A10-7700K holds a clear edge in the recorded benchmarks. Across the head-to-head tests, the A10-7700K wins both available comparisons, with a 14.7% lead in Geekbench multi-core and a 6.9% lead in Geekbench single-core. The AMD PRO A10-8750B, despite having higher base and boost clocks, does not translate that into a benchmark advantage in these measurements.

For a builder choosing between these two, the A10-7700K is the stronger pick based purely on performance data. It also has an unlocked multiplier, which means it can be adjusted for higher clocks, a feature the PRO A10-8750B lacks. The PRO A10-8750B is not without merit: it has a higher base clock of 3.60 GHz versus 3.40 GHz, and a higher boost clock of 4.00 GHz versus 3.80 GHz, but the recorded scores do not reflect that advantage. The PRO chip is positioned as a professional or commercial part, but the benchmark results indicate the consumer-oriented A10-7700K is the faster option in the tests that were run.

The verdict is straightforward: if you want the better benchmark performer and the flexibility of an unlocked multiplier, the A10-7700K is the choice. If you need a part with a higher stock clock and a commercial part number, the PRO A10-8750B exists, but you will sacrifice benchmark performance and overclocking capability.

Where Each One Wins

The AMD A10-7700K wins in every recorded head-to-head benchmark. In Geekbench multi-core, it scores 1155 against 985 for the PRO A10-8750B, a 14.7% advantage. In Geekbench single-core, it scores 447 against 416, a 6.9% advantage. These are the only two tests where both chips have directly comparable data, and the A10-7700K takes both.

The AMD PRO A10-8750B does not win any of the head-to-head tests. However, it has its own set of benchmark results that the A10-7700K lacks. The PRO chip records a Cinebench R15 multi-core score of 254, a Cinebench R20 multi-core score of 1060, a Cinebench R20 single-core score of 149, a Cinebench R23 multi-core score of 2525, and a Cinebench R23 single-core score of 356. These numbers cannot be directly compared to the A10-7700K because the database has no Cinebench results for that chip, but they provide a reference point for the PRO part's absolute performance.

In practical terms, the A10-7700K wins where it matters for general computing and lightly threaded workloads, based on the Geekbench results. The PRO A10-8750B, with its higher clocks, might be expected to win in clock-sensitive tasks, but the data does not support that expectation in the tests that were recorded. The PRO chip's only advantage is its stock clock speed and its commercial positioning, not its measured performance.

Architecture Differences

Both processors are built on AMD's Steamroller architecture, using a 28 nm process node from GlobalFoundries. They share the same transistor count of 2,411 million and the same die size of 245 mm². The codenames differ: the PRO A10-8750B is from the Godaveri family, while the A10-7700K is from the Kaveri family. Both are listed as generation A10, with the respective codename in parentheses.

The cache layout is identical. Both have 256 KB of L1 cache and 4 MB of L2 cache, with no L3 cache present. Memory support is also the same: DDR3 memory, dual-channel bus, and a memory bandwidth of 34.1 GB/s. Neither supports ECC memory. PCIe connectivity matches as well, with Gen 3 and 16 lanes available from the CPU.

The integrated graphics are the same: Radeon R7 on both chips. The socket is also shared, with both using AMD Socket FM2+. The core and thread counts are equal at 4 cores and 4 threads. The key architectural difference, aside from the codename, is the multiplier. The A10-7700K has an unlocked multiplier, while the PRO A10-8750B does not. This means the A10-7700K can be overclocked, while the PRO part is locked to its stock clock settings.

The release dates differ: the A10-7700K launched on January 13, 2014, while the PRO A10-8750B launched on September 28, 2015. Both are end-of-life products. The part numbers are distinct, reflecting their different market roles, but the underlying silicon is essentially the same Steamroller design with minor clock and feature variations.

Head-to-Head Benchmarks

The only directly comparable benchmarks in the database are the two Geekbench tests. The AMD A10-7700K wins both convincingly.

In Geekbench multi-core, the A10-7700K scores 1155, while the PRO A10-8750B scores 985. That is a delta of 14.7% in favor of the A10-7700K. This is a significant margin for two chips with the same core count and same architecture. The higher clock speed of the PRO chip, 3.60 GHz base and 4.00 GHz boost, did not help it in this test. The A10-7700K, with its 3.40 GHz base and 3.80 GHz boost, still managed to outperform it by a wide margin.

In Geekbench single-core, the A10-7700K scores 447, while the PRO A10-8750B scores 416. The delta is 6.9% in favor of the A10-7700K. This is a smaller but still consistent lead. Single-core performance is often tied to clock speed, but here the lower-clocked A10-7700K wins. The data suggests that the A10-7700K's silicon or its configuration delivers better per-clock performance in Geekbench, despite the PRO chip's higher rated clocks.

Beyond these two tests, the PRO A10-8750B has additional benchmark results that are not available for the A10-7700K. In Cinebench R15 multi-core, the PRO chip scores 254. In Cinebench R20, it scores 1060 multi-core and 149 single-core. In Cinebench R23, it scores 2525 multi-core and 356 single-core. These numbers cannot be compared to the A10-7700K, but they show that the PRO chip is a capable 4-core part in its own right. The average benchmark score for the PRO A10-8750B is 821, while the A10-7700K has an average of 801. The PRO chip's average is slightly higher, but that includes all its Cinebench results, which the A10-7700K lacks.

The head-to-head tally is clear: the A10-7700K wins 2 out of 2 tests, and the PRO A10-8750B wins 0. The percentile ranking for both chips is the same at 22, meaning they sit in a similar position relative to all CPUs in the database, but the direct comparison favors the A10-7700K.
