Intel Core i5-4570R vs Intel Core i7-3770T Comparison

The Intel Core i5-4570R and Intel Core i7-3770T are two end-of-life desktop processors that, despite similar average benchmark scores, present very different performance profiles depending on the workload. The data shows the i7-3770T dominates in Cinebench tests across the board, while the i5-4570R delivers a massive victory in Geekbench. This split is unusual and dictates a clear choice based on the software you run.

Where Each One Wins

The i7-3770T is the clear winner for multi-threaded rendering and CPU-intensive compute tasks. In every Cinebench test — R15, R20, and R23 — the i7-3770T outperforms the i5-4570R by a consistent margin of roughly 16%. For single-threaded Cinebench workloads, the i7-3770T also leads, with a 16.9% advantage in R15, a 16.1% lead in R20, and a 16% lead in R23. If your work involves 3D rendering, video encoding, or any application that relies on the Cinebench-style rendering engine, the i7-3770T is the superior choice.

Conversely, the i5-4570R is the winner in Geekbench, which measures a broader set of everyday tasks including encryption, image processing, and memory performance. The i5-4570R scores 49.9% higher in Geekbench multicore and 59.3% higher in Geekbench singlecore compared to the i7-3770T. This indicates that in general-purpose computing scenarios, database operations, or office productivity suites that leverage Geekbench-like workloads, the i5-4570R is significantly faster.

The overall average benchmark score is nearly identical, with the i5-4570R at 1318 and the i7-3770T at 1314, a delta of just 0.3%. This means neither CPU is a universal winner; instead, the choice hinges entirely on whether your primary applications are Cinebench-style (rendering) or Geekbench-style (system-level tasks).

Head-to-Head Benchmarks

The most striking result in the data is the Geekbench disparity. The i5-4570R scores 2872 in Geekbench multicore, while the i7-3770T manages only 1916. That is a 49.9% win for the i5-4570R. The single-core Geekbench result is even more lopsided: 943 for the i5-4570R versus 592 for the i7-3770T, a 59.3% difference. These are not marginal gains; the i5-4570R is nearly 60% faster in single-threaded Geekbench performance.

The Cinebench results tell the opposite story. In Cinebench R23 multicore, the i7-3770T scores 4611, while the i5-4570R scores 3879, giving the i7-3770T a 15.9% lead. The pattern holds in Cinebench R20 multicore, where the i7-3770T scores 1936 versus 1629, again a 15.9% margin. In Cinebench R15 multicore, the scores are 464 and 390, respectively. The single-core Cinebench tests follow a similar trend, with the i7-3770T leading by 16.9% in R15 (65 vs 54), 16.1% in R20 (273 vs 229), and 16% in R23 (651 vs 547).

The aggregate benchmarks reflect this split. The i7-3770T wins 6 out of 8 head-to-head tests, but the two it loses are by enormous margins. The i5-4570R wins only 2 tests, but those wins are so decisive that they pull its average score to within 0.3% of the i7-3770T.

Specification Differences

The most significant specification difference is thread count. The i7-3770T has 4 cores and 8 threads, while the i5-4570R has 4 cores and 4 threads. This explains the i7-3770T's advantage in multi-threaded Cinebench workloads, as it can process twice as many threads simultaneously.

Clock speeds differ as well. The i7-3770T has a base clock of 2.50 GHz and a boost clock of 3.70 GHz. The i5-4570R has a higher base clock of 2.70 GHz but a lower boost clock of 3.20 GHz. The i7-3770T's higher boost clock likely contributes to its lead in single-threaded Cinebench tests.

The cache configuration is also different. The i5-4570R has 4 MB of shared L3 cache, while the i7-3770T has 8 MB of shared L3 cache. This doubled L3 cache in the i7-3770T can improve performance in workloads that benefit from larger data residency.

Memory bandwidth figures are listed for the i5-4570R at 25.6 GB/s, but no memory bandwidth is listed for the i7-3770T. Both support dual-channel DDR3 memory and have the same PCIe configuration: Gen 3 with 16 lanes (CPU only).

The socket and physical dimensions differ, with the i5-4570R using Intel BGA 1364 and the i7-3770T using Intel Socket 1155. The TDP also differs, with the i5-4570R rated at 65W and the i7-3770T at 45W, making the i7-3770T more power-efficient on paper.

Architecture Differences

The two CPUs are built on different microarchitectures. The i5-4570R is based on Haswell, with the codename "Crystal Well," while the i7-3770T is based on Ivy Bridge. Both use a 22 nm process node from Intel, but the transistor counts differ: the i5-4570R has 1,700 million transistors on a 260 mm² die, while the i7-3770T has 1,400 million transistors on a 160 mm² die.

The i5-4570R's integrated graphics is the Intel Iris Pro 5200, which is a more advanced GPU than the Intel HD 4000 found in the i7-3770T. This makes the i5-4570R a better choice for systems relying on integrated graphics for display output or light GPU-accelerated tasks.

L1 and L2 caches are identical between the two, with 64 KB of L1 per core and 256 KB of L2 per core. The key architectural difference is the L3 cache, where the i7-3770T's 8 MB is double the i5-4570R's 4 MB. The i7-3770T also has Hyper-Threading, which the i5-4570R lacks, providing 8 threads versus 4.

The release dates show the i7-3770T came first, launching in April 2012, while the i5-4570R launched in June 2013. Both are now end-of-life for the i5-4570R, with no production status listed for the i7-3770T.

The Verdict

The data presents a clear, workload-dependent verdict. If your software suite is dominated by Cinebench-style rendering tasks — think 3D animation, visual effects, or CPU-based rendering — the Intel Core i7-3770T is the better processor. It delivers a consistent 15.9% to 16.9% performance advantage across all Cinebench tests, thanks to its 8 threads and higher boost clock of 3.70 GHz. The i7-3770T also consumes less power with a 45W TDP versus the i5-4570R's 65W, making it the more efficient option for sustained rendering workloads.

If your work involves Geekbench-style tasks — such as general productivity, web browsing, office applications, or system-level number crunching — the Intel Core i5-4570R is the clear winner. Its 49.9% lead in Geekbench multicore and 59.3% lead in singlecore are overwhelming, indicating that for these common tasks, the i5-4570R will feel significantly snappier. The i5-4570R also offers the superior Intel Iris Pro 5200 integrated graphics, which is a practical advantage for a system without a discrete GPU.

For a balanced user who runs a mix of workloads, the average benchmark scores are nearly identical, with the i5-4570R only 0.3% ahead. In that case, the choice comes down to specific software and hardware needs. The i7-3770T's Hyper-Threading and larger 8 MB L3 cache make it the better choice for heavily multi-threaded applications. The i5-4570R's massive Geekbench wins and superior integrated graphics make it better for everyday computing. The i7-3770T is the rendering workhorse; the i5-4570R is the general-purpose system builder's pick.
