AMD PRO A8-9600 vs Intel Core i7-950 Comparison

The Verdict

The benchmark data presents a clear, if narrow, picture. Across all five recorded Cinebench tests, the AMD PRO A8-9600 wins every single head-to-head matchup against the Intel Core i7-950. The margins are consistently small, ranging from a 1.4% advantage in multi-core R15 and R23 tests to a 1.8% lead in the R20 single-core test. The average benchmark score reinforces this: the AMD part scores 971, while the Intel part scores 957, a difference of roughly 1.5%. Both processors sit at the 26th percentile among all CPUs in the database, meaning they occupy the same performance tier overall.

For users choosing strictly between these two, the data points to the AMD PRO A8-9600 as the better performer in every measured workload. The Intel Core i7-950, however, remains a viable alternative if platform compatibility with older DDR3 memory or Socket 1366 motherboards is a requirement. The AMD chip is the safer pick for raw compute performance, but the Intel chip is not far behind, and its triple-channel memory interface could be a factor in memory-heavy tasks, though the database records no bandwidth figure for the Intel part to confirm this advantage.

Architecture Differences

The two processors come from different eras and design philosophies. The AMD PRO A8-9600 uses the Excavator architecture, built on Bristol Ridge, and is manufactured on a 28 nm process at GlobalFoundries. It integrates 3,100 million transistors on a 250 mm² die. The Intel Core i7-950 uses the older Nehalem architecture, codenamed Bloomfield, built on a 45 nm process at Intel. It contains 731 million transistors on a 263 mm² die. The transistor count difference is substantial, with the AMD chip packing over four times as many transistors, likely due to its integrated graphics and newer process node.

Core and thread configurations differ notably. Both chips have 4 physical cores, but the Intel Core i7-950 supports Hyper-Threading, giving it 8 threads. The AMD PRO A8-9600 has only 4 threads. Despite this thread deficit, the AMD chip still wins all multi-core benchmarks, indicating that its higher base clock and per-core efficiency compensate for the lack of simultaneous multithreading. The AMD chip runs at a 3.10 GHz base clock with a 3.40 GHz boost, while the Intel chip runs at 3.07 GHz base with a 3.33 GHz boost. The AMD chip has a slight clock advantage at both ends.

Cache hierarchies are structured completely differently. The AMD PRO A8-9600 has 320 KB of L1 cache and 2 MB of L2 cache, with no L3 cache at all. The Intel Core i7-950 has 64 KB of L1 and 256 KB of L2 per core, plus a shared 8 MB L3 cache. The Intel chip's large shared L3 cache is a significant architectural advantage, yet it does not translate into benchmark wins in the recorded data. Memory support also diverges: the AMD chip uses DDR4 with dual-channel configuration and a recorded bandwidth of 38.4 GB/s, while the Intel chip uses DDR3 with triple-channel support and no recorded bandwidth figure. The AMD chip also features integrated Radeon R7 graphics, whereas the Intel chip has no integrated graphics. PCIe support differs, with the AMD chip offering Gen 3 with 8 lanes from the CPU, while the Intel chip has Gen 2.

Head-to-Head Benchmarks

The recorded head-to-head results show a consistent pattern of narrow AMD victories. In the Cinebench R15 multi-core test, the AMD PRO A8-9600 scores 284 against the Intel Core i7-950's 280, a 1.4% delta. This is the closest margin of any test. Moving to Cinebench R20 multi-core, the AMD chip scores 1184 versus 1167 for the Intel chip, a 1.5% delta. The R20 single-core test shows the AMD chip at 167 and the Intel chip at 164, a 1.8% delta, the largest margin in the entire dataset.

The Cinebench R23 results continue the trend. In the multi-core test, the AMD PRO A8-9600 scores 2820, while the Intel Core i7-950 scores 2780, a 1.4% delta. In the R23 single-core test, the AMD chip scores 398 against 392 for the Intel chip, a 1.5% delta. Across all five tests, the AMD chip wins by an average margin of roughly 1.5%. The Intel chip's 8 threads do not help it overcome the AMD chip's clock speed and IPC advantages in these specific workloads. The largest single-core delta (1.8% in R20) suggests the AMD chip has a slightly stronger per-thread performance profile, which is noteworthy given the Intel chip's larger L3 cache and Hyper-Threading support.

Where Each One Wins

The AMD PRO A8-9600 wins in every single recorded benchmark category. It takes the multi-core tests in R15, R20, and R23, and it also wins the single-core tests in R20 and R23. This means the AMD chip is the better choice for both heavily threaded workloads and lightly threaded tasks, based on the available data. The wins are narrow but consistent, suggesting a small but real performance advantage across the board.

The Intel Core i7-950 has no benchmark wins in the recorded data, but it does have architectural features that could matter in scenarios not covered by Cinebench. Its 8 MB shared L3 cache and triple-channel DDR3 memory interface could provide benefits in memory-bandwidth-sensitive applications, though the database does not record a bandwidth figure to confirm this. The Intel chip's 8 threads could also help in workloads that scale well beyond 4 threads, but the recorded Cinebench multi-core results show the AMD chip still wins despite having only 4 threads. For users on a legacy DDR3 platform with Socket 1366 motherboards, the Intel chip is the only compatible option, but for raw performance, the AMD chip is the winner in every measured test.
