Intel Core i5-4670R vs Intel Core i7-3770T Comparison

Head-to-Head Benchmarks

The recorded data shows a remarkably consistent pattern across all six head-to-head Cinebench tests: the Intel Core i7-3770T wins every single matchup, but by a narrow margin. The victories range from 3.2% to 3.8%, never exceeding 4%. This is not a dominant performance gap; it is a steady, modest advantage that repeats itself across different rendering workloads and scoring methodologies.

In Cinebench R15 multi-core, the i7-3770T scores 464 against the i5-4670R's 448, a 3.6% lead. The single-core test shows a similar story: 65 versus 63, a 3.2% edge. Moving to Cinebench R20, the i7-3770T posts 1936 in multi-core versus 1868 for the i5-4670R, again a 3.6% difference, while single-core shows 273 versus 263, a 3.8% gap. The newest workload, Cinebench R23, follows the same trajectory: the i7-3770T scores 4611 multi-core against 4448, a 3.7% lead, and 651 single-core against 627, a 3.8% advantage.

What is notable is the absence of any test where the i5-4670R wins. The benchmark database records zero wins for the i5-4670R across all six head-to-head tests. However, the margins are tight enough that in real-world usage, the difference would be perceptible but not dramatic. The i7-3770T's advantage is consistent, which suggests a structural reason rather than a workload-specific quirk.

The average benchmark scores reinforce this picture. The i7-3770T has an average score of 1314 across all recorded benchmarks, while the i5-4670R sits at 1286. That is a 2.2% difference in the overall average, smaller than the head-to-head deltas because the averages include Geekbench results for the i7-3770T that have no direct counterpart in the i5-4670R's record. The i7-3770T's Geekbench multi-core score is 1916 and single-core is 592, but the i5-4670R has no Geekbench entries in the database.

Both processors sit at the 35th percentile among all CPUs in the database, meaning they occupy the same tier of overall performance relative to the broader market. The nearest rivals for the i7-3770T include the AMD Athlon Gold 7220U at an average score of 1311 (a 0.2% delta) and the Intel Core i5-4570R at 1318 (a -0.3% delta). The i5-4670R's nearest rivals include the Intel Core i5-3570 at 1286 (0% delta) and the Intel Core i5-3570K at 1293 (a -0.6% delta). These neighboring scores indicate that both chips sit in a crowded performance band where small architectural differences determine the ordering.

Architecture Differences

The two processors come from different Intel generations and microarchitectures. The i7-3770T is built on Ivy Bridge, a 22 nm process, while the i5-4670R is Haswell, also on 22 nm. Both use the same transistor count of 1,400 million, but the die sizes differ: the i7-3770T measures 160 mm², while the i5-4670R is larger at 177 mm². The larger die on the i5-4670R likely reflects the integration of a more capable graphics unit and other Haswell-era changes, though the transistor count being identical suggests the extra area is not used for additional compute cores.

Core and thread counts are a key differentiator. The i7-3770T has 4 cores and 8 threads, enabling simultaneous multithreading. The i5-4670R has 4 cores and 4 threads, with no hyper-threading support. This explains the i7-3770T's multi-core lead despite having a lower base clock. The i7-3770T runs at 2.50 GHz base and 3.70 GHz boost, while the i5-4670R starts at 3.00 GHz base and also boosts to 3.70 GHz. The i5-4670R has a higher base clock by 500 MHz, but the i7-3770T's extra threads compensate in threaded workloads.

Cache hierarchies differ substantially. The i7-3770T has 8 MB of shared L3 cache, while the i5-4670R has only 4 MB. Both have 64 KB L1 per core and 256 KB L2 per core. The doubled L3 cache on the i7-3770T is a meaningful advantage for workloads that benefit from larger shared pools of cached data, particularly when multiple threads access the same data structures.

The integrated graphics are another major divergence. The i7-3770T uses Intel HD 4000, while the i5-4670R uses Intel Iris? Pro 5200. The question mark in the database entry for the i5-4670R's graphics suggests some uncertainty, but the naming indicates a substantially more advanced graphics solution. The Iris Pro line was designed for better 3D performance and media capabilities, which could matter for systems without a discrete GPU.

Memory support is DDR3 for both, but the bus configuration differs. The i7-3770T uses dual-channel memory, while the database does not record a memory bus width for the i5-4670R. Power envelopes are also different: the i7-3770T has a TDP of 45 watts, while the i5-4670R draws 65 watts. This makes the i7-3770T a more power-efficient part despite its higher thread count.

Socket and packaging are completely different. The i7-3770T uses Intel Socket 1155, a conventional desktop socket, while the i5-4670R uses Intel BGA 1364, a ball-grid array package that is soldered directly to the motherboard. This means the i5-4670R is not upgradeable in the traditional sense; it is designed for embedded or all-in-one systems. The i7-3770T also has PCIe Gen 3 with 16 lanes from the CPU, while the i5-4670R has no PCIe information recorded.

The i5-4670R has an unlocked multiplier, making it overclockable, while the i7-3770T is locked. This is unusual for a BGA part, but it suggests the i5-4670R was aimed at enthusiasts in compact form factors. The i7-3770T's part number is SR0PQ, while the i5-4670R has no part number recorded.

Where Each One Wins

The i7-3770T wins all six head-to-head benchmarks, but the nature of those wins points to specific use cases. Its advantage is largest in single-core tests, where it leads by 3.2% to 3.8%, and nearly equal in multi-core tests, where it leads by 3.6% to 3.7%. The single-core edge comes from the same 3.70 GHz boost clock as the i5-4670R but with additional cache and architectural optimizations from the extra threads and larger L3.

For multi-threaded workloads, the i7-3770T's 8 threads versus 4 threads is the defining factor. Video encoding, 3D rendering, and compilation tasks that scale with thread count will see the i7-3770T pull ahead, even though its base clock is lower. The 45-watt TDP also makes the i7-3770T a better fit for power-constrained systems or small form factor builds where thermal headroom is limited.

The i5-4670R's strengths lie outside the recorded benchmark suite. Its unlocked multiplier and higher base clock of 3.00 GHz mean that in lightly threaded, latency-sensitive tasks where boost clocks are sustained, it could match or exceed the i7-3770T, but the data does not show this. The Iris? Pro 5200 integrated graphics are a significant upgrade over HD 4000, so systems relying solely on integrated graphics for casual gaming or GPU-accelerated media processing would favor the i5-4670R.

The i5-4670R also has an active production status, while the i7-3770T's status is not recorded. This suggests the i5-4670R may still be available for new designs, whereas the i7-3770T is likely end-of-life. For embedded or industrial applications where long-term availability matters, the i5-4670R could be the safer choice despite losing in raw benchmarks.

The Verdict

The data points to a clear but narrow winner in the i7-3770T. Across every recorded benchmark, it outperforms the i5-4670R by a consistent 3% to 4% margin. The reasons are evident: 8 threads versus 4 threads, double the L3 cache, and a lower TDP that makes it more efficient. Anyone prioritizing CPU compute performance, especially in multi-threaded applications, should choose the i7-3770T based on these measurements.

The i5-4670R is not without rationale, but its case rests on factors outside the benchmark suite. The unlocked multiplier and higher base clock could appeal to overclockers, while the Iris? Pro 5200 integrated graphics are a substantial upgrade over HD 4000. The active production status also matters for long-term procurement. However, for pure processing power as recorded in the database, the i7-3770T wins all six head-to-head tests, and that is the decisive statistic.

Both chips sit at the 35th percentile among all CPUs, meaning they are mid-pack performers by modern standards. The i7-3770T's nearest rival is the AMD Athlon Gold 7220U, a full half-point behind, and the i5-4670R's closest competitor is the Intel Core i5-3570, which matches its score exactly. This is a segment where small margins separate chips, and the i7-3770T consistently holds the edge.
