CPU Comparison

The AMD A8-9600 and Intel Core i7-950 represent two very different eras of desktop computing, yet the benchmark data places them in a near-identical performance tier. Both processors achieve the 26th percentile in the global CPU ranking, with the AMD part averaging a score of 962 and the Intel part averaging 957. The head-to-head results show the A8-9600 winning all five Cinebench comparisons, though the margins are consistently under one percent. This is a matchup defined by architectural philosophy rather than outright performance dominance, where a modern, power-efficient quad-core with integrated graphics squares off against an older, high-TDP eight-thread processor from the Bloomfield generation.

FAQ

Q: Which processor has the higher multi-core performance in Cinebench R23?

A: The AMD A8-9600 edges out the Intel Core i7-950 in Cinebench R23 multi-core, scoring 2797 against 2780, a delta of 0.6 percent. This margin is consistent with the R20 multi-core result, where AMD leads 1174 to 1167.

Q: How do the single-core scores compare between these two CPUs?

A: The A8-9600 holds a slight lead in both single-core tests. In Cinebench R20 single-core, it scores 165 versus 164 for the i7-950 (0.6 percent delta), and in R23 single-core, it scores 394 versus 392 (0.5 percent delta).

Q: What is the difference in the number of threads each processor can handle?

A: The Intel Core i7-950 supports 8 threads across its 4 cores via Hyper-Threading, while the AMD A8-9600 is a true 4-core, 4-thread part without simultaneous multithreading.

Q: Which processor has a higher thermal design power (TDP) requirement?

A: The Intel Core i7-950 has a TDP of 130 watts, exactly double the 65-watt TDP of the AMD A8-9600. This indicates a substantially higher power draw for the older Intel chip.

Q: Do both processors support the same type of system memory?

A: No. The AMD A8-9600 supports DDR4 memory on a dual-channel bus, while the Intel Core i7-950 uses DDR3 memory on a triple-channel bus. The AMD platform also lists a memory bandwidth of 38.4 GB/s, whereas the Intel part has no bandwidth figure listed.

Q: Are these processors still in production?

A: The AMD A8-9600 is listed as active in production, with a release date of July 26, 2017. The Intel Core i7-950 is end-of-life, having been released on June 1, 2009.

Head-to-Head Benchmarks

The benchmark suite results present a clean sweep for the AMD A8-9600, though the magnitudes are exceptionally small. In Cinebench R15 multi-core, the A8-9600 scores 281 against the i7-950's 280, giving AMD a 0.4 percent victory. The R20 multi-core test shows a similar story: 1174 for AMD versus 1167 for Intel, a 0.6 percent gap. The R23 multi-core run, which is the most recent and demanding workload in the set, yields 2797 for the A8-9600 and 2780 for the i7-950, again a 0.6 percent difference.

Single-core results follow the same pattern. The R20 single-core test has the A8-9600 ahead by a single point, 165 to 164, translating to a 0.6 percent delta. The R23 single-core test is equally tight, with AMD leading 394 to 392, a 0.5 percent margin. Across all five recorded benchmarks, the AMD processor wins with deltas ranging from 0.4 to 0.6 percent.

These margins are within the noise floor of most benchmark runs, yet the consistency is notable. The A8-9600 never loses a single comparison, even though the i7-950 possesses twice the thread count. The practical takeaway is that the two processors deliver functionally equivalent application performance, with the AMD silicon managing a marginal but repeatable edge. For reference, the A8-9600's nearest rival is the Intel Pentium Gold G5500T, which scores 963 (a -0.1 percent delta), while the i7-950 sits alongside the AMD Opteron 4386 at a perfect 0.0 percent delta.

Where Each One Wins

Looking strictly at the benchmark outcomes, the AMD A8-9600 wins every recorded test. Its advantages are most pronounced in the multi-core Cinebench R20 and R23 runs, where it leads by 0.6 percent. This suggests that for rendering workloads that scale across cores, the modern Excavator architecture manages to keep pace with, and slightly surpass, the older Nehalem design despite having half the threads. The single-core wins, while smaller in absolute point difference, reinforce that the A8-9600 has superior per-thread efficiency.

The Intel Core i7-950 has no benchmark wins in this dataset, but its architectural strengths point to scenarios where it could close the gap. With 8 threads available, it is positioned to handle heavily threaded applications that can utilize more than four hardware threads. In workloads where the A8-9600's lack of SMT becomes a bottleneck, the i7-950's extra logical processors could provide an advantage that these specific Cinebench tests do not fully capture. Additionally, the triple-channel DDR3 memory controller offers a wider memory bus, which could benefit memory-bandwidth-sensitive tasks, though no bandwidth figure is listed for the Intel part to quantify this.

For general desktop use, the AMD A8-9600 is the more complete package due to its integrated Radeon R7 graphics, an option the i7-950 entirely lacks. This makes the AMD processor a viable choice for systems without a discrete GPU, whereas the Intel part requires a separate graphics card for any display output. The A8-9600 also operates at a 65-watt TDP, making it far easier to cool and more suitable for compact or energy-conscious builds, while the i7-950's 130-watt TDP demands a more robust cooling solution.

Specification Differences

The core specifications diverge significantly despite similar base and boost clocks. The AMD A8-9600 runs at a 3.10 GHz base clock with a 3.40 GHz boost, while the Intel Core i7-950 operates at 3.07 GHz base and 3.33 GHz boost. The A8-9600 has 4 cores and 4 threads, whereas the i7-950 has 4 cores and 8 threads. TDP is a major differentiator: 65 watts for AMD versus 130 watts for Intel.

Memory support is another clear division. The AMD part uses DDR4 memory in a dual-channel configuration with a listed bandwidth of 38.4 GB/s, while the Intel part uses DDR3 in a triple-channel setup with no bandwidth figure provided. The PCIe capabilities also differ, with the A8-9600 offering PCIe Gen 3 with 8 lanes (CPU only), and the i7-950 offering PCIe Gen 2 without a lane count listed. The AMD processor includes integrated Radeon R7 graphics, while the Intel processor has no integrated graphics. The A8-9600 is compatible with AMD Socket AM4, and the i7-950 uses Intel Socket 1366.

Architecture Differences

The two CPUs are built on fundamentally different architectures and manufacturing processes. The AMD A8-9600 uses the Excavator architecture on a 28 nm process node, fabricated by GlobalFoundries. It contains 3,100 million transistors on a 250 mm² die. The Intel Core i7-950 uses the Nehalem architecture on a 45 nm process node, fabricated by Intel, with 731 million transistors on a 263 mm² die. This means the AMD chip packs over four times the transistor count into a slightly smaller die area, a testament to the process and design improvements made between 2009 and 2017.

Cache hierarchies also reflect their different design goals. The A8-9600 has a 320 KB L1 cache and a 2 MB L2 cache, with no L3 cache present. The i7-950 has a 64 KB per-core L1 cache, a 256 KB per-core L2 cache (totaling 1 MB for four cores), and a shared 8 MB L3 cache. The Intel part's large L3 cache is a classic high-end desktop feature from the Nehalem era, while the AMD part relies on a smaller total cache footprint but benefits from the newer Excavator core design.

The i7-950 is based on the Bloomfield codename and belongs to the first generation of Core i7 processors, released in mid-2009. The A8-9600 is based on the Bristol Ridge codename within the A8 series, released in mid-2017. Both processors have locked multipliers, preventing easy overclocking. The Intel part is end-of-life, while the AMD part remains active in production. Neither processor supports ECC memory, and both target the desktop market segment.
