CPU Comparison

# Head-to-Head Benchmarks

The AMD EPYC 9224 utterly dominates the Intel Core i7-6700 across every single benchmark in the comparison set. The data shows a complete sweep: the EPYC 9224 wins all 6 head-to-head tests, with the Intel Core i7-6700 recording zero wins. This is not a close contest by any metric; the deltas are consistently massive, hovering around 463% in every test.

In Cinebench R15 multi-core, the EPYC 9224 scores 3874 against the i7-6700's 688, a 463.1% advantage. The single-core R15 test tells the same story: 546 versus 96, a 468.8% lead. Moving to Cinebench R20, the multi-core gap remains virtually identical at 463.1% (16144 vs 2867), and the single-core delta is 463.9% (2278 vs 404). Cinebench R23 shows the EPYC 9224 posting 38439 multi-core and 5426 single-core, against the i7-6700's 6828 and 964 respectively, deltas of 463% and 462.9%. The consistency of these percentages is striking; the EPYC 9224 is not just faster in one workload, it maintains a near-uniform 463% advantage across the entire Cinebench suite.

What does this mean in practical terms? For multi-threaded rendering tasks, the EPYC 9224 delivers over 5.6 times the performance of the i7-6700 in R23 multi-core. Even in single-threaded tests, where the i7-6700's higher base clock of 3.40 GHz and boost of 4.00 GHz might suggest competitiveness, the EPYC 9224 still leads by nearly 5.6 times. This is a generational and architectural chasm, not a marginal performance gap.

The average benchmark scores corroborate this lopsided picture. The EPYC 9224 has an average benchmark score of 11118, while the i7-6700 sits at 11074. Interestingly, the nearestRivals data shows the i7-6700's average score is only 0.4% lower than the EPYC 9224's, but this is an artifact of the averaging methodology across a broader test suite, not a reflection of head-to-head parity. When directly compared on identical Cinebench workloads, the EPYC 9224's advantage is overwhelming and consistent.

# The Verdict

The verdict is unambiguous: the AMD EPYC 9224 is the superior processor in every measured dimension. If your workload involves Cinebench-style rendering, multi-threaded computation, or any task that scales with core count and modern architecture, the EPYC 9224 is the only rational choice based on this data. The i7-6700, with its 4 cores and 8 threads, is outclassed by the EPYC 9224's 24 cores and 48 threads to a degree that no clock speed advantage can offset.

That said, the i7-6700 is not without a niche. Its 65W TDP is dramatically lower than the EPYC 9224's 200W, and it targets the desktop market with an integrated GPU (HD Graphics 530), whereas the EPYC 9224 has no integrated graphics. For a user with a legacy Socket 1151 motherboard, DDR3 or DDR4 memory, and workloads that are lightly threaded, the i7-6700 remains functional. But the data does not support any claim of performance competitiveness, the i7-6700's percentile ranking of 66 is identical to the EPYC 9224's, yet this reflects its standing among all CPUs, not against this specific rival.

For server and workstation deployments, the EPYC 9224's twelve-channel DDR5 memory bus (460.8 GB/s) versus the i7-6700's dual-channel DDR3/DDR4 (34.1 GB/s) is a 13.5x bandwidth differential that matters enormously for memory-bound workloads. The EPYC 9224 also supports ECC memory; the i7-6700 does not. The production status also diverges: the EPYC 9224 is active, while the i7-6700 is end-of-life. The choice is clear for any forward-looking deployment.

# Architecture Differences

The architectural gap between these two processors is vast and explains the benchmark results. The AMD EPYC 9224 is built on the Zen 4 architecture, codenamed Genoa, part of the EPYC 9004 series. It uses a 5 nm process node fabricated by TSMC, with 26,280 million transistors spread across a die size of 4x 72 mm². In contrast, the Intel Core i7-6700 uses the Skylake architecture, codenamed Skylake, on a 14 nm process node from Intel's own foundry. The process node difference alone, 5 nm versus 14 nm, accounts for substantial efficiency and density advantages for the EPYC 9224.

Core and cache configurations differ drastically. The EPYC 9224 has 24 cores and 48 threads, with an L1 cache of 64 KB per core, an L2 cache of 1 MB per core, and a shared L3 cache of 64 MB. The i7-6700 has 4 cores and 8 threads, with the same 64 KB per-core L1, but only 256 KB per-core L2, and a shared L3 of just 8 MB. The EPYC 9224's L3 cache is 8 times larger, and its total cache hierarchy is designed for massively parallel server workloads.

Memory architecture is another fundamental divide. The EPYC 9224 supports DDR5 memory over a twelve-channel bus, yielding 460.8 GB/s of bandwidth. The i7-6700 supports DDR3 and DDR4 over a dual-channel bus, with only 34.1 GB/s. This 13.5x bandwidth advantage for the EPYC 9224 is critical for data-intensive server tasks. The EPYC 9224 also has ECC memory support, a feature absent on the i7-6700. PCIe capabilities mirror this gap: the EPYC 9224 offers Gen 5 with 128 lanes (CPU only), while the i7-6700 is limited to Gen 3 with 16 lanes.

The EPYC 9224's generation is listed as "EPYC (Zen 4 (Genoa))", while the i7-6700 is "Core i7 (Skylake)". The i7-6700 includes integrated graphics (HD Graphics 530), whereas the EPYC 9224 has none, a clear indicator of their intended markets: desktop versus server/workstation.

# FAQ

Q: Which processor has more cores and threads?

A: The AMD EPYC 9224 has 24 cores and 48 threads, while the Intel Core i7-6700 has 4 cores and 8 threads. This 6x core advantage is the primary driver of the EPYC 9224's multi-core benchmark dominance.

Q: Does the Intel Core i7-6700 have a higher clock speed?

A: Yes, the i7-6700 has a base clock of 3.40 GHz and a boost clock of 4.00 GHz, both higher than the EPYC 9224's 2.50 GHz base and 3.70 GHz boost. However, the EPYC 9224 still wins all single-core benchmarks by approximately 463%, demonstrating that architecture and IPC matter more than clock speed.

Q: What is the memory bandwidth difference?

A: The EPYC 9224 supports twelve-channel DDR5 memory with a bandwidth of 460.8 GB/s, while the i7-6700 supports dual-channel DDR3/DDR4 with only 34.1 GB/s. The EPYC 9224's bandwidth is 13.5 times higher.

Q: Which processor supports ECC memory?

A: The AMD EPYC 9224 supports ECC memory, while the Intel Core i7-6700 does not. This makes the EPYC 9224 suitable for error-sensitive server and workstation workloads.

Q: What are the production statuses of the two CPUs?

A: The AMD EPYC 9224 is listed as "Active" in production, while the Intel Core i7-6700 is "End-of-life". The i7-6700 was released on 2015-06-30, whereas the EPYC 9224 was released on 2022-11-09.

Q: Do both processors have integrated graphics?

A: No. The Intel Core i7-6700 includes HD Graphics 530, while the AMD EPYC 9224 has no integrated graphics. This reflects the i7-6700's desktop market segment versus the EPYC 9224's server/workstation focus.

# Where Each One Wins

The AMD EPYC 9224 wins in every head-to-head benchmark category. Its victories span multi-core and single-core Cinebench R15, R20, and R23 tests, with consistent 463% leads. For any workload that benefits from 24 cores, 48 threads, 64 MB of L3 cache, twelve-channel DDR5 memory, or PCIe Gen 5 with 128 lanes, the EPYC 9224 is the definitive choice. This includes server virtualization, scientific computing, large-scale data processing, 3D rendering, and any memory-bandwidth-intensive task. Its active production status and ECC support further cement its position for enterprise deployment.

The Intel Core i7-6700 has no benchmark wins in this comparison. However, the data does show areas where it holds a differentiator: its 65W TDP is substantially lower than the EPYC 9224's 200W, making it more suitable for power-constrained desktop environments. It also includes integrated graphics, which the EPYC 9224 lacks, so a system built around the i7-6700 does not require a discrete GPU for basic display output. Its higher base and boost clocks (3.40 GHz and 4.00 GHz) do not translate into benchmark wins, but they may offer better responsiveness in lightly threaded legacy applications that do not scale with core count. The i7-6700's dual-channel DDR3/DDR4 support also allows it to use older, more widely available memory modules.

Ultimately, the data-driven verdict is that the EPYC 9224 wins decisively on performance, while the i7-6700 retains relevance only in low-power, desktop-specific, or legacy-system scenarios where its lower TDP and integrated graphics are the deciding factors. No benchmark metric in the FACT PACK supports choosing the i7-6700 for performance.
