CPU Comparison

The Intel Core i5-4670 and Intel Core i5-760 are both quad-core desktop processors, but they represent very different eras of Intel's design philosophy. The benchmark data shows the i5-4670 winning all six head-to-head comparisons, yet the margins are remarkably slim, ranging from 0.6% to 1.5%. This makes the i5-4670 the faster chip in every measured workload, but the i5-760 remains surprisingly competitive given its older architecture and significantly lower clock speeds. The i5-4670 is the clear choice for anyone building on a modern platform, while the i5-760, despite its age, still holds its own in raw compute tasks.

The Verdict

The data is unambiguous: the Intel Core i5-4670 wins every single benchmark in the comparison. It takes the Cinebench R15 multicore test with a score of 469 against the i5-760's 466, a margin of 0.6%. That lead expands slightly in single-core R15, where the i5-4670 scores 66 versus 65, a 1.5% advantage. The pattern holds across newer test versions: in Cinebench R20 multicore, the i5-4670 posts 1957 against 1942 (0.8% ahead), and in R23 multicore, it scores 4660 versus 4624 (0.8% ahead). Single-core results in R20 (275 vs 273) and R23 (657 vs 652) also favor the i5-4670 by 0.7% and 0.8%, respectively.

Who should pick which? For any user prioritizing raw CPU throughput in Cinebench-style workloads, the i5-4670 is the superior part. It wins all six tests, and its average benchmark score of 1347 edges out the i5-760's 1337. The i5-4670 also sits in the 36th percentile of all CPUs, one point higher than the i5-760's 35th percentile. However, the i5-760 is not obsolete by any means, its performance is within 1% of the i5-4670 in most tests, making it a viable option for legacy systems that already use the older Socket 1156 platform. The i5-4670, with its newer Haswell architecture and lower 84W TDP, is the better recommendation for a new build or an upgrade, but the i5-760's end-of-life status and comparable scores mean it should not be dismissed outright for cost-constrained retrofits.

Architecture Differences

The two processors are separated by three years of silicon evolution, and the architectural changes are stark. The i5-4670 is built on Intel's 22 nm process node using the Haswell architecture, with a die size of 177 mm² and 1,400 million transistors. In contrast, the i5-760 uses the older 45 nm node and the Nehalem architecture (codename Lynnfield), packing 774 million transistors into a much larger 296 mm² die. This explains the i5-4670's efficiency advantage: it delivers higher performance while consuming less power.

Clock speeds tell a similar story. The i5-4670 runs at a 3.40 GHz base clock and boosts up to 3.80 GHz. The i5-760 is slower on paper, with a 2.80 GHz base and a 3.33 GHz boost. Despite the i5-760's lower clocks, it nearly matches the i5-4670 in benchmarks, which points to the Nehalem architecture's strength in integer-heavy workloads. The cache layout differs as well: the i5-4670 has 6 MB of shared L3 cache, while the i5-760 has 8 MB of shared L3 cache. Both have 64 KB of L1 and 256 KB of L2 per core, so the larger L3 on the older chip partially compensates for its clock deficit.

Integrated graphics are a major differentiator. The i5-4670 includes Intel HD 4600 graphics, while the i5-760 has no integrated GPU at all. This means the i5-4670 can power a display without a discrete graphics card, whereas the i5-760 requires a separate GPU. The i5-4670 also supports PCIe Gen 3, while the i5-760 is limited to PCIe Gen 2 with 16 lanes from the CPU only. Memory support is identical in type (DDR3) and bus width (dual-channel), but the i5-4670's newer memory controller is likely more efficient, even though raw bandwidth figures are not provided.

Head-to-Head Benchmarks

The biggest win for the i5-4670 comes in the Cinebench R15 single-core test, where it scores 66 against the i5-760's 65, a 1.5% advantage. This is the largest delta in the entire comparison, and it reflects the i5-4670's higher boost clock and newer architecture's better instruction-level parallelism. In multi-threaded workloads, the margin narrows: R15 multicore shows a 0.6% lead (469 vs 466), while R20 multicore and R23 multicore both show a 0.8% lead (1957 vs 1942 and 4660 vs 4624, respectively).

The single-core results in R20 and R23 are almost identical, with the i5-4670 leading by 0.7% (275 vs 273) and 0.8% (657 vs 652), respectively. These small deltas are notable because they suggest that the i5-760's older architecture is not a significant bottleneck in these tests, the i5-4670's higher clock speed (3.80 GHz vs 3.33 GHz boost) is just enough to edge ahead. In multicore tests, the i5-760's larger 8 MB L3 cache appears to help it stay close, despite the i5-4670's 22 nm process advantage and lower TDP.

The data shows a consistent pattern: the i5-4670 wins every test, but never by more than 1.5%. This means the i5-760 is not a slouch, it trades blows with newer parts in its nearest rival list, including the Intel Core i5-2500K, which it trails by only 0.6% in average score (1337 vs 1329). The i5-4670, for its part, is nearly tied with the Intel Xeon W-2104, which has an average score of 1350, a 0.2% gap. These benchmark results indicate that both chips are clustered in a performance tier where architectural efficiency and clock speed matter less than the specific workload.

Specification Differences

The two processors differ in several key specifications, though they share a core count of 4 and thread count of 4. The most significant differences are:

• Base clock: 3.40 GHz (i5-4670) vs 2.80 GHz (i5-760)
• Boost clock: 3.80 GHz (i5-4670) vs 3.33 GHz (i5-760)
• TDP: 84 W (i5-4670) vs 95 W (i5-760)
• Socket: Intel Socket 1150 (i5-4670) vs Intel Socket 1156 (i5-760)
• Architecture: Haswell (i5-4670) vs Nehalem (i5-760)
• Process node: 22 nm (i5-4670) vs 45 nm (i5-760)
• Transistors: 1,400 million (i5-4670) vs 774 million (i5-760)
• Die size: 177 mm² (i5-4670) vs 296 mm² (i5-760)
• L3 cache: 6 MB (i5-4670) vs 8 MB (i5-760)
• PCIe version: Gen 3 (i5-4670) vs Gen 2, 16 Lanes (CPU only) (i5-760)
• Integrated graphics: Intel HD 4600 (i5-4670) vs none (i5-760)
• Release date: 2013-06-01 (i5-4670) vs 2010-07-17 (i5-760)
• Production status: not specified (i5-4670) vs End-of-life (i5-760)

The i5-4670's 22 nm process allows it to pack more transistors into a smaller die, which directly contributes to its lower TDP and higher clock speeds. The i5-760's larger 8 MB L3 cache is a notable counterpoint, but it does not overcome the clock deficit. Both processors support DDR3 memory in dual-channel mode, and neither supports ECC memory. Neither chip has an unlocked multiplier, so overclocking is not an option straight out of the box. The part numbers are SR14D for the i5-4670 and SLBRP for the i5-760.
