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

Head-to-Head Benchmarks

The benchmark record splits into two distinct sets of outcomes, and the pattern is unusually clear. The Intel Core i7-3770T wins every Cinebench test, while the Intel Core i5-4670T wins both Geekbench tests. That is a 6 to 2 split in the i7-3770T's favor, but the margins on each side tell a more nuanced story than the raw win count suggests.

Starting with Cinebench R15, the i7-3770T posts a multicore score of 464 against 384 for the i5-4670T, a lead of 20.8%. The single-core result in the same suite shows 65 versus 54, which is also a 20.4% advantage. The R20 multicore test repeats the pattern: 1936 for the i7-3770T versus 1604, a 20.7% gap. Single-core R20 shows 273 versus 226, again 20.8% in favor of the i7-3770T. The R23 suite rounds out the sweep with a multicore score of 4611 against 3820 (20.7%) and a single-core score of 651 versus 539 (20.8%).

These margins are remarkably consistent across all six Cinebench tests, hovering between 20.4% and 20.8% regardless of workload or renderer version. That consistency suggests a structural advantage rather than a workload-specific quirk. The i7-3770T's extra threads are the most obvious explanation, as the chip has 8 threads against the i5-4670T's 4. But the single-core results also favor the i7-3770T, which points to higher clock speeds playing a role as well.

The Geekbench results flip the narrative. In the multicore test, the i5-4670T scores 2563 against 1916 for the i7-3770T, a 25.2% difference. The single-core test shows an even larger gap: 977 versus 592, which is a 39.4% advantage for the i5-4670T. These are substantial margins, and they are not small enough to dismiss as test noise.

The divergence between Cinebench and Geekbench is striking. The i7-3770T leads by roughly one-fifth in one suite, while the i5-4670T leads by one-quarter to nearly two-fifths in the other. This is not a case of one chip being universally faster. The architecture, thread count, and clock behavior interact differently with each benchmark's instruction mix and scheduling model.

The Verdict

The data points in two directions, and the correct choice depends entirely on the workload. For Cinebench-based rendering tasks, the Intel Core i7-3770T is the clear winner. Its 20.8% lead in R15 multicore, 20.7% in R20 multicore, and 20.7% in R23 multicore are decisive and consistent. Anyone running render loops or CPU-bound video encoding that resembles Cinebench's workload should favor the i7-3770T.

For Geekbench-style workloads, the Intel Core i5-4670T is the stronger part. The 25.2% multicore lead and the 39.4% single-core lead are substantial enough to matter in everyday application responsiveness, browser performance, and single-threaded productivity tasks. The i5-4670T also carries the newer Haswell architecture, which shows up in its memory subsystem and IPC improvements.

The overall average benchmark score favors the i7-3770T: 1314 versus 1271, a difference of roughly 3.4%. Both parts sit at the 35th percentile across all CPUs in the database, so neither is a high-flying performer by modern standards. The i7-3770T's nearest rivals include the AMD Athlon Gold 7220U at 1311 (0.2% behind), the Intel Core i5-4570R at 1318 (0.3% ahead), and the Intel Celeron G6900E and G6900T at 1321 (0.5% ahead). The i5-4670T's nearest rivals include the Intel Atom x7425E at 1273 (0.2% ahead), the Intel Core i5-4430S at 1274 (0.2% ahead), the Intel Core i3-1005G1 at 1265 (0.5% behind), and the Intel Xeon W-2102 at 1264 (0.6% behind). These rival positions show both chips clustered tightly with similar average scores.

The verdict is not a blanket recommendation. It is a workload split. The i7-3770T wins render-heavy workloads by a wide margin. The i5-4670T wins Geekbench-style tasks by an even wider margin. Users who know their application mix should pick accordingly.

Where Each One Wins

The i7-3770T wins every Cinebench test in the record. That includes R15, R20, and R23, both single-core and multicore. The consistent 20.4% to 20.8% advantage across all six tests indicates a broad suitability for render workloads. The 8 threads versus 4 threads likely explains the multicore wins, while the higher boost clock of 3.70 GHz versus 3.30 GHz helps explain the single-core wins. The larger shared L3 cache of 8 MB versus 6 MB may also contribute to the render performance.

The i5-4670T wins both Geekbench tests. The single-core score of 977 versus 592 is a 39.4% lead, which is the largest margin in the entire comparison. The multicore score of 2563 versus 1916 is a 25.2% lead. These results suggest the Haswell architecture delivers better per-clock performance in integer and floating-point workloads that Geekbench exercises. The i5-4670T's newer design, despite having fewer threads, manages to outpace the older Ivy Bridge chip in this suite.

For mixed workloads, the choice is less obvious. The i7-3770T has the higher average benchmark score (1314 versus 1271) and wins more individual tests (6 versus 2). The i5-4670T has the higher peak scores in its winning tests. A user who runs a variety of applications might prefer the i7-3770T for its broader consistency, while a user who knows their work is single-threaded might prefer the i5-4670T.

Architecture Differences

The two chips come from different Intel architecture generations. The i7-3770T is built on Ivy Bridge, while the i5-4670T is built on Haswell. Both use a 22 nm process node and are manufactured by Intel, with 1,400 million transistors each. The die size differs slightly: the i7-3770T measures 160 mm², while the i5-4670T measures 177 mm².

The core and thread configuration is a key differentiator. The i7-3770T has 4 cores and 8 threads, enabling simultaneous multithreading. The i5-4670T has 4 cores and 4 threads, with no hyper-threading. This explains part of the Cinebench multicore gap. The clock speeds also differ: the i7-3770T has a base clock of 2.50 GHz and a boost clock of 3.70 GHz, while the i5-4670T has a base clock of 2.30 GHz and a boost clock of 3.30 GHz.

Cache sizes differ as well. Both chips have 64 KB of L1 cache per core and 256 KB of L2 cache per core. The shared L3 cache is larger on the i7-3770T at 8 MB, compared to 6 MB on the i5-4670T. The memory support is identical in type: DDR3 memory with a dual-channel bus. Neither chip supports ECC memory.

The PCIe implementation differs. The i7-3770T lists PCIe Gen 3 with 16 lanes (CPU only). The i5-4670T lists PCIe Gen 3 without a lane count specified. The integrated graphics differ as well: the i7-3770T carries Intel HD 4000, while the i5-4670T carries Intel HD 4600. The newer Haswell chip includes a more capable integrated GPU, which may matter for systems without a discrete graphics card.

The release dates are separated by about a year. The i7-3770T was released in April 2012, while the i5-4670T was released in June 2013. Both are locked multipliers, so neither supports unlocked overclocking. The part numbers are SR0PQ for the i7-3770T and SR14P for the i5-4670T. The generation labels are "Core i7 (Ivy Bridge)" and "Core i5 (Haswell)", respectively, both in the desktop market segment.

The architectural differences map cleanly onto the benchmark results. The i7-3770T's extra threads and higher clocks drive its Cinebench wins. The i5-4670T's newer Haswell core design and higher IPC drive its Geekbench wins. The 6 MB versus 8 MB L3 cache difference is notable, but the benchmark results suggest the newer core design matters more than the larger cache in single-threaded workloads.
