AMD A4 PRO-7350B

The AMD A4 PRO-7350B is a dual-core desktop processor from the Kaveri generation, built on the Steamroller architecture and 28 nm process node. Benchmark results place it in the 7th percentile of all CPUs, with an average benchmark score of 451, positioning it as a low-end part that trades raw performance for basic functionality. Its nearest rivals—the Intel Core i3-540, Intel Celeron G1610, Intel Celeron J4005, and Intel Xeon E5335—all cluster within a 0.3% performance delta, indicating that this chip competes in a tightly packed tier of legacy and entry-level processors.

Single-Thread vs Multi-Thread Behavior

The A4 PRO-7350B’s benchmark splits reveal a processor heavily skewed toward single-threaded efficiency over parallel throughput. In Cinebench R23, the single-core score of 185 versus a multi-core score of 1,312 yields a ratio of roughly 7.1:1, meaning the multi-core result is only about 7 times the single-core score—expected for a 2-core, 2-thread part with no simultaneous multithreading. This indicates that workloads relying on a single thread, such as older office applications, light web browsing, or legacy software, will see proportionally better performance than tasks that can use both cores.

In Cinebench R20, the single-core score of 77 and multi-core score of 551 show a similar pattern, with the multi-core figure being approximately 7.2 times the single-core result. The Cinebench R15 multi-core score of 132 reinforces this, as it is a modest absolute number. The data suggests that while the processor can execute two threads simultaneously, the lack of additional threads or cores means scaling in multi-threaded environments is linear at best, with no efficiency gains from hyper-threading or extra cache. Real-world implications: spreadsheet recalculation, document formatting, and single-threaded scripting will perform near the processor’s ceiling, while video encoding, 3D rendering, or compilation workloads will see only marginal gains from the second core, and performance will lag far behind any modern multi-core part.

Platform and Compatibility

The A4 PRO-7350B uses the AMD Socket FM2+ interface, which is designed for the Kaveri generation of processors. It is built on the Steamroller architecture with a 28 nm process node from GlobalFoundries, containing 2,411 million transistors on a 245 mm² die. Memory support is limited to DDR3, operating in dual-channel mode, with a peak memory bandwidth of 29.9 GB/s. ECC memory is not supported, which excludes it from error-correcting workstation or server configurations. The processor provides PCIe Gen 3 with 16 lanes available from the CPU, supporting a single discrete graphics card or multiple lower-bandwidth devices, though the integrated Radeon R5 graphics can serve as a basic display output without a dedicated GPU.

The platform’s upgrade path is constrained by the FM2+ socket, which is end-of-life. Users are limited to other Kaveri or later FM2+ processors, but the production status of the A4 PRO-7350B itself is end-of-life, meaning no new units are manufactured. The processor has a locked multiplier, so overclocking via frequency adjustments is not possible, limiting enthusiast tuning. For system builders, this means any purchase is for legacy or refurbished systems, and the DDR3 memory requirement further ties it to older motherboards and RAM. The lack of L3 cache—only 128 KB L1 and 1 MB shared L2—combined with the modest memory bandwidth, positions this chip as a basic entry point for light computing, not a platform for expansion or future-proofing.

Who Should Consider It

Given the benchmark data, the A4 PRO-7350B is suitable for users whose workloads are predominantly single-threaded and low-intensity. For office tasks such as word processing, email, and spreadsheet use, the Cinebench R23 single-core score of 185 indicates adequate responsiveness for legacy software, though modern browsers with many tabs may strain the 2-thread limit. Light photo editing or basic media playback (non-4K) would fall within its capabilities, but the integrated Radeon R5 graphics and 29.9 GB/s memory bandwidth do not support demanding visual workloads.

Gamers should avoid this processor. With a 7th percentile rank and multi-core scores of 551 (Cinebench R20) and 1,312 (Cinebench R23), it cannot sustain modern game physics or AI threads, and the lack of additional threads means frame pacing will suffer. Content creators—video editors, 3D modelers, or software developers—will find the multi-core performance inadequate; the Cinebench R15 multi-core score of 132 is roughly a tenth of what contemporary entry-level chips achieve. The processor is best suited for secondary machines, thin clients, or dedicated single-purpose systems (e.g., print servers, basic kiosks) where the low cost of legacy hardware outweighs performance needs. Users requiring ECC memory or high-bandwidth storage (beyond PCIe Gen 3) must look elsewhere.

How It Compares

Against the Intel Core i3-540, the A4 PRO-7350B shows a 0% delta in average benchmark score, meaning they perform identically in aggregate. The i3-540, an older dual-core part, matches the A4’s throughput, but the A4 offers newer integrated graphics and DDR3 support, while the i3-540 has a different memory controller. For single-threaded tasks, the A4’s higher boost clock of 3.80 GHz likely gives it an edge, but the overall scores are statistically tied.

The Intel Celeron G1610 is 0.2% behind the A4 PRO-7350B, a negligible difference. Both are dual-core parts without hyper-threading, and the Celeron’s lower clock speeds (not listed) are offset by its newer architecture. The A4’s integrated Radeon R5 graphics provide a display output advantage over the Celeron, which requires a separate GPU, but raw CPU performance is nearly identical.

The Intel Celeron J4005 trails by 0.3%, a margin that falls within measurement noise. The J4005 is a low-power dual-core, and the A4’s higher TDP of 65 W allows for higher sustained clocks, but benchmark results show no practical difference. The A4’s PCIe Gen 3 support is superior to the J4005’s older PCIe standard, but for basic tasks, users would not notice the difference.

The Intel Xeon E5335 also sits 0.3% behind, despite being a quad-core server processor from an earlier era. The Xeon’s four cores are offset by its lower per-core performance, resulting in a tie with the A4’s two faster cores. The A4’s lack of ECC memory and lower thread count makes it less suitable for server workloads, but for desktop use, the A4’s newer architecture and integrated graphics are practical advantages.

Power and Thermals

The A4 PRO-7350B has a TDP of 65 W, which classifies it as a mainstream desktop processor requiring standard cooling. This TDP is typical for mid-2010s dual-core parts, and it implies that a stock air cooler—either AMD’s bundled solution or a third-party low-profile cooler—is sufficient. The 28 nm process node and 2,411 million transistors on a 245 mm² die contribute to a moderate heat density, but the dual-core design keeps peak temperatures manageable under load.

The 65 W TDP also dictates system power supply requirements: a standard 300 W PSU is adequate for a basic build with integrated graphics, though adding a discrete GPU would necessitate a higher-wattage unit (not specified in the data). Thermal throttling is unlikely with a capable air cooler, given the low core count and modest clock speeds (3.40 GHz base, 3.80 GHz boost). For compact or fanless builds, the 65 W TDP is at the upper edge of passive cooling viability, so active cooling is recommended. Compared to modern low-power chips (e.g., 10–15 W parts), the A4’s 65 W TDP is high for the performance delivered, but it is consistent with its 2014 release era.

Benchmark Performance

The A4 PRO-7350B’s benchmark scores tell a consistent story of a low-end dual-core processor. In Cinebench R23, the multi-core score of 1,312 and single-core score of 185 indicate that the chip’s performance is heavily dependent on clock speed rather than core count. The single-core score is roughly 14% of the multi-core score (185/1,312), which is expected for a 2-thread part. In Cinebench R20, the multi-core score of 551 and single-core score of 77 show a similar ratio, with the multi-core being about 7.2 times the single-core. The Cinebench R15 multi-core score of 132 is the lowest of the three generations, reflecting older benchmark scaling.

Compared to its nearest rivals, the A4 PRO-7350B is statistically indistinguishable. The Intel Core i3-540 has a 0% delta, meaning identical average scores of 451. The Intel Celeron G1610 is 0.2% behind, with an average score of 452 (the A4’s 451 divided by 0.998). The Intel Celeron J4005 and Intel Xeon E5335 are both 0.3% behind, with average scores of 452 as well. These deltas are within a single point, confirming that the A4 PRO-7350B delivers essentially the same aggregate performance as four different rivals spanning multiple generations and price tiers.

The percentile ranking of 7% underscores how far behind modern CPUs this part sits. In multi-threaded workloads, the 551 Cinebench R20 score is less than a tenth of what a contemporary 6-core processor achieves (not specified, but implied by the percentile). The single-core score of 185 in Cinebench R23 is also weak, as modern entry-level chips exceed 1,000 in that test. The data suggests that the A4 PRO-7350B is only viable for extremely light tasks, and even then, its performance is comparable to decade-old Intel parts. The lack of L3 cache (none listed) and 1 MB of shared L2 further limit its ability to handle data-intensive workloads, making it a poor choice for anything beyond basic office or browsing use.
