AMD PRO A10-8750B vs Intel Core i5-3380M Comparison

The Verdict

The benchmark data presents a close contest with a clear split. The AMD PRO A10-8750B wins the majority of recorded tests, taking 5 out of 7 head-to-head matchups, while the Intel Core i5-3380M secures 2 wins. However, the margin of victory matters. The AMD part wins every Cinebench test by a razor-thin margin, between 0.7% and 0.8%, which is effectively a tie in real-world terms. The Intel part, by contrast, wins the Geekbench tests by substantial margins: 7.1% in multi-core and 21.4% in single-core.

Looking at the aggregate data, the Intel Core i5-3380M records an average benchmark score of 838, while the AMD PRO A10-8750B sits at 821. Both processors land in the 22nd percentile of all CPUs in the database, meaning they occupy the same performance tier. The Intel chip’s nearest rivals, including the Intel Core i5-5200U and Intel Xeon X3450, score within 0.1% of its average. The AMD chip’s closest competitor, the Intel Xeon E5540, is 0.1% behind, and the AMD A10 PRO-7850B is 0.8% ahead.

For a user deciding between these two, the choice hinges on the workload. If the task is Geekbench-style testing, which often reflects general system responsiveness and certain application types, the Intel Core i5-3380M is the stronger pick. If the workload is Cinebench rendering, the AMD PRO A10-8750B holds a slight edge, though the margin is so small that it would not be perceptible. The Intel part is a mobile processor with a 35W TDP, while the AMD part is a desktop chip with a 95W TDP, so system-level considerations beyond raw compute may influence the decision.

Where Each One Wins

The Intel Core i5-3380M dominates in Geekbench results. In the Geekbench multi-core test, it scores 1055 against the AMD’s 985, a 7.1% advantage. The single-core Geekbench test shows an even larger gap: 505 versus 416, a 21.4% lead for Intel. This pattern suggests the Intel architecture delivers stronger per-thread performance in this benchmark, likely benefiting from its higher boost clock relative to its base clock and its Ivy Bridge design.

The AMD PRO A10-8750B wins every Cinebench variant recorded. Starting with Cinebench R15 multi-core, it scores 254 versus Intel’s 252, a 0.8% gap. In Cinebench R20 multi-core, it scores 1060 versus 1051, again 0.8% ahead. The single-core Cinebench R20 test shows 149 versus 148, a 0.7% edge. Cinebench R23 multi-core gives the AMD part a 2525 against 2504, and single-core gives it 356 against 353. These wins are consistent but narrow.

For a use-case breakdown, the data suggests the Intel chip is better suited for applications that mirror Geekbench’s workload mix, particularly those sensitive to single-thread speed. The AMD chip is marginally better for sustained multi-threaded rendering workloads as represented by Cinebench, though the difference is statistically negligible. The AMD part also offers a higher base clock of 3.60 GHz and boost clock of 4.00 GHz, which may help in lightly threaded tasks, but the benchmark results do not show this translating into a Cinebench single-core win of any magnitude.

Architecture Differences

The Intel Core i5-3380M is built on the Ivy Bridge architecture using a 22 nm process at Intel’s foundry. It features 2 physical cores with 4 threads via Hyper-Threading. The base clock is 2.90 GHz with a boost clock of 3.60 GHz. The thermal design power is 35W, reflecting its mobile market segment. It uses the Intel Socket G2 (988B) and supports DDR3 memory in a dual-channel configuration. The cache hierarchy includes 64 KB of L1 per core, 256 KB of L2 per core, and 3 MB of shared L3 cache. The integrated graphics are Intel HD 4000. The die size is 118 mm².

The AMD PRO A10-8750B uses the Steamroller architecture, codenamed Godaveri, built on a 28 nm process at GlobalFoundries. It has 4 physical cores and 4 threads, with no SMT. The base clock is 3.60 GHz and the boost clock reaches 4.00 GHz. The TDP is 95W, which is substantially higher than the Intel part, and it is a desktop processor. It uses the AMD Socket FM2+ and supports DDR3 dual-channel memory with a recorded bandwidth of 34.1 GB/s. The cache configuration is 256 KB of L1 and 4 MB of L2, with no L3 cache. The integrated graphics are Radeon R7. The transistor count is 2,411 million on a 245 mm² die. It also provides PCIe Gen 3 with 16 lanes from the CPU.

The core count difference is notable: the AMD chip has twice the physical cores, but the Intel chip uses simultaneous multithreading to reach 4 threads. The lack of L3 cache on the AMD part is compensated by a larger L2 pool. The process node advantage goes to Intel at 22 nm versus 28 nm, though the AMD chip has a higher clock speed on paper. The AMD part is end-of-life according to the database, while the Intel part’s production status is not specified.

Head-to-Head Benchmarks

The head-to-head data shows a near-sweep for the AMD PRO A10-8750B in Cinebench, but the margins are so slight that they fall within measurement noise. In Cinebench R15 multi-core, the AMD scores 254 against Intel’s 252, a delta of -0.8%. The R20 multi-core test repeats the pattern: 1060 versus 1051, again -0.8%. The R20 single-core test gives AMD a 149 against Intel’s 148, a -0.7% delta. Cinebench R23 multi-core shows 2525 versus 2504, -0.8%, and R23 single-core shows 356 versus 353, -0.8%.

The Geekbench results tell a different story. In Geekbench multi-core, the Intel Core i5-3380M scores 1055 against the AMD’s 985, a 7.1% advantage. This is a clear win for Intel. The Geekbench single-core test is even more decisive: Intel scores 505, AMD scores 416, giving Intel a 21.4% lead. This is the largest delta in the entire head-to-head set.

Interpreting these numbers, the AMD PRO A10-8750B’s Cinebench wins are consistent but trivial in magnitude. A 0.8% difference in a rendering benchmark would not translate into a perceptible speedup during a render job. The Intel part’s Geekbench wins, however, are substantial. A 21.4% single-core advantage suggests the Intel architecture has a significant per-thread performance edge in that benchmark’s workload. The multi-core Geekbench gap of 7.1% also favors Intel despite the AMD chip having twice the physical cores.

The average benchmark scores reinforce the overall picture. Intel’s 838 average is 17 points higher than AMD’s 821. Both processors land at the 22nd percentile, but the Intel chip’s nearest rivals include the Intel Core i5-5200U at a 0.1% delta, while the AMD chip’s nearest rival is the Intel Xeon E5540 also at 0.1%. The AMD part’s closest competitor from its own family, the AMD A10 PRO-7850B, sits 0.8% ahead, meaning the PRO A10-8750B is slightly below its sibling in the database.

For a buyer, the data suggests the Intel Core i5-3380M is the better choice for single-threaded response and general application performance as measured by Geekbench. The AMD PRO A10-8750B offers a marginal edge in Cinebench rendering, but that edge is so small it would not be noticeable. The Intel chip also does this with a 35W TDP, which is far lower than the AMD’s 95W, a relevant consideration for system design even if power efficiency is not directly benchmarked here.
