AMD A10 PRO-7850B vs AMD Athlon X4 830 Comparison

Where Each One Wins

The AMD Athlon X4 830 and the AMD A10 PRO-7850B are close siblings from the same Kaveri family, but the recorded benchmark data separates them into two distinct profiles. The Athlon X4 830 dominates the Cinebench suite, which stresses sustained multi-threaded and single-threaded CPU work. Its Cinebench R15 multicore score of 248, R20 multicore score of 1035, and R23 multicore score of 2465 show a processor that handles rendering workloads with consistency. The A10 PRO-7850B, by contrast, has no Cinebench entries in the database; its only recorded results are Geekbench scores, with a multicore score of 1194 and a singlecore score of 462.

The A10 PRO-7850B wins in the Geekbench arena, where its 4.00 GHz boost clock and 3.70 GHz base clock give it a measurable edge over the Athlon X4 830's 3.40 GHz boost and 3.00 GHz base. In real-world terms, the Athlon X4 830 is the better choice for CPU-centric productivity and rendering tasks, while the A10 PRO-7850B is positioned for workloads that benefit from higher clock speeds and its integrated Radeon R7 graphics. The Athlon X4 830 has no integrated graphics at all, so any system built around it requires a discrete GPU. The A10 PRO-7850B, with its Radeon R7, can run display output without an add-in card, which makes it the more self-contained option for basic desktop use.

The average benchmark scores reflect this split: the Athlon X4 830 posts an average score of 848, while the A10 PRO-7850B sits slightly lower at 828. The Athlon's percentile ranking among all CPUs is 23, versus 22 for the A10 PRO-7850B. These are marginal differences, but they align with the benchmark pattern: the Athlon is a touch faster in aggregate, while the A10 PRO-7850B carries the graphics advantage. The data suggests that if the workload is purely computational, the Athlon X4 830 is the safer pick; if the workload includes light graphics or media playback, the A10 PRO-7850B's integrated Radeon R7 makes it the more versatile part.

Architecture Differences

Both processors are built on the Steamroller architecture, using the Kaveri codename, and both are manufactured on a 28 nm process at GlobalFoundries. They share identical transistor counts of 2,411 million and an identical die size of 245 mm². The cache hierarchy is also the same: 256 KB of L1 cache and 4 MB of L2 cache, with no L3 cache present on either chip. Memory support is DDR3 over a dual-channel bus, with a memory bandwidth of 34.1 GB/s. Neither part supports ECC memory, and both use PCIe Gen 3 with 16 lanes from the CPU. Both fit the AMD Socket FM2+.

The key architectural difference lies in the clock speeds and the integrated graphics. The Athlon X4 830 runs at a 3.00 GHz base clock and boosts to 3.40 GHz, while the A10 PRO-7850B runs at 3.70 GHz base and boosts to 4.00 GHz. That is a 700 MHz advantage at base and a 600 MHz advantage at boost for the A10 PRO-7850B, which explains its higher Geekbench singlecore score. Thermal design power also differs: the Athlon X4 830 is rated at 65 W, while the A10 PRO-7850B carries a 95 W TDP. The higher TDP reflects both the higher clocks and the presence of the Radeon R7 integrated graphics on the A10 PRO-7850B.

The Athlon X4 830 has a fully unlocked multiplier, making it a candidate for overclocking, while the A10 PRO-7850B has a locked multiplier. This is a meaningful distinction for enthusiasts: the Athlon can be pushed beyond its stock 3.40 GHz boost, potentially closing the clock gap with the A10 PRO-7850B, whereas the A10 PRO-7850B is fixed at its factory settings. The release dates differ as well: the A10 PRO-7850B was released on 2014-07-30, while the Athlon X4 830 has no recorded release date in the database. Both parts are end-of-life and target the desktop market.

The part numbers confirm the family resemblance: the Athlon X4 830 is AD830XYBI44JA, and the A10 PRO-7850B is AD785BXBI44JA. The architecture, process, memory controller, and PCIe implementation are identical; only the clock speeds, TDP, graphics block, and multiplier lock status separate them. The absence of L3 cache on both parts is worth noting, as it places them in a performance tier where L2 latency and clock speed do the heavy lifting.

Head-to-Head Benchmarks

The head-to-head benchmark list in the database is empty, so the comparison must rely on the individual benchmark suites each processor was tested with. The Athlon X4 830 has five recorded Cinebench results, while the A10 PRO-7850B has two recorded Geekbench results. There is no direct overlap in test names, which means a strict apples-to-apples comparison is not possible from the recorded data. However, the average benchmark scores and rival deltas provide context.

The Athlon X4 830's average score of 848 places it 0.4% behind the Intel Xeon X5492, which averages 852, and 0.6% ahead of both the Intel Core i7-3520M and the AMD FX-8800P, both of which average 843. It is also 0.9% behind the Intel Core i5-5250U, which averages 856. These deltas are small, indicating that the Athlon X4 830 sits in a crowded performance band. Its Cinebench R23 singlecore score of 348 and multicore score of 2465 show that it scales reasonably well with all four cores active, and its Cinebench R20 singlecore score of 146 against a multicore score of 1035 suggests a scaling factor of roughly seven times, which is typical for a four-core, four-thread part with no simultaneous multithreading.

The A10 PRO-7850B's average score of 828 places it 0.8% behind the Intel Core i5-3360M, which averages 835, and 1.1% behind the Intel Xeon X3450, which averages 837. It is 0.9% ahead of both the AMD PRO A10-8750B and the Intel Xeon E5540, which average 821 and 820 respectively. The A10 PRO-7850B's Geekbench singlecore score of 462 is its strongest recorded result, and its multicore score of 1194 shows that the higher clock speed translates into a solid single-thread showing. The Athlon X4 830's best recorded single-core result, a Cinebench R23 singlecore score of 348, cannot be directly compared to the Geekbench number, but the clock speed gap is visible in the data.

What the benchmarks do show is that the Athlon X4 830, despite lower clocks, achieves a higher average score across its tested suite. The A10 PRO-7850B's higher clocks do not overcome the fact that its recorded Geekbench scores, when averaged, land below the Athlon's Cinebench average. The Athlon X4 830 also benefits from a 65 W TDP, which is 30 W lower than the A10 PRO-7850B's 95 W rating, making it the more power-efficient part on paper.

The Verdict

The data points to a clear split. The AMD Athlon X4 830 is the better pure CPU. Its Cinebench R15, R20, and R23 scores demonstrate solid multicore performance, and its average benchmark score of 848 outranks the A10 PRO-7850B's 828. The Athlon X4 830 also has an unlocked multiplier, allowing manual overclocking, and a lower 65 W TDP. For a desktop built around a discrete GPU and focused on rendering, compilation, or other CPU-bound tasks, the Athlon X4 830 is the stronger choice.

The AMD A10 PRO-7850B is the better all-in-one part. Its integrated Radeon R7 graphics eliminate the need for a separate GPU in basic systems, and its higher base and boost clocks, 3.70 GHz and 4.00 GHz, give it a single-thread advantage that shows in the Geekbench singlecore score of 462. The locked multiplier is a limitation, but for a user who does not overclock and wants a single chip that can handle both processing and display output, the A10 PRO-7850B is the practical option.

The percentile rankings are nearly identical, 23 for the Athlon X4 830 and 22 for the A10 PRO-7850B, reinforcing that these are comparable performers in the broader CPU landscape. The nearest rival data shows both chips trading places with similar Intel and AMD parts, with deltas under 1.1% in all cases. Neither processor is a standout in the current market, and both are end-of-life. The choice comes down to whether the user needs integrated graphics and higher clocks, or prefers an unlocked multiplier and lower power draw.
