Intel Core i5-4570R vs Intel Core i5-6500T Comparison

Head-to-Head Benchmarks

The benchmark comparison between the Intel Core i5-4570R and the Intel Core i5-6500T is a consistent, if narrow, victory for the Skylake part. Across the eight recorded tests, the i5-6500T takes seven wins, with the sole exception being the Geekbench multicore test. That headline result, a 1% lead for the i5-4570R (2872 versus 2843), is the closest margin in the entire dataset and represents the one area where the Haswell chip's older architecture manages to edge ahead in parallel throughput.

Every Cinebench test tells the same story. In Cinebench R15 multicore, the i5-6500T scores 408 against 390 for the i5-4570R, a delta of -4.4% from the latter's perspective. The single-core R15 result shows a slightly larger gap: 57 versus 54, a -5.3% difference. Moving to Cinebench R20, the multicore scores are 1702 and 1629 (-4.3%), while single-core lands at 240 versus 229 (-4.6%). The most recent Cinebench R23 iteration repeats the pattern: multicore 4054 against 3879 (-4.3%), and single-core 572 against 547 (-4.4%). These deltas are remarkably consistent, clustering between 4.3% and 5.3% across all Cinebench workloads, which suggests the i5-6500T's advantage is structural rather than workload-specific.

The Geekbench results break that uniformity. While the i5-6500T dominates single-core Geekbench by a substantial 7.2% margin (1016 versus 943), the multicore score flips: the i5-4570R posts 2872, narrowly beating the i5-6500T's 2843. That 1% swing is the only instance where the older part wins, and it is importantly the absolute scores are very close, indicating that neither CPU has a decisive edge in heavily threaded Geekbench workloads.

Looking at the broader database context, the i5-4570R sits at the 35th percentile of all CPUs with an average benchmark score of 1318. Its nearest rivals include the Intel Celeron G6900E and G6900T, both with an average score of 1321 (a -0.2% delta), and the Intel Core i7-3770T at 1314 (a +0.3% delta). The i5-6500T is slightly higher, at the 36th percentile with an average score of 1362. Its closest competitor is the Intel Core i5-8365UE, which matches it exactly at 1362 (0% delta), while the Intel Core i7-3820QM trails by 0.3% at 1366. In practical terms, the i5-6500T's average score is roughly 3.3% higher than the i5-4570R's, a modest but consistent uplift that shows up across nearly every benchmark.

Where Each One Wins

The i5-6500T is the clear winner for single-threaded performance and most multi-threaded rendering workloads. Its Cinebench R15, R20, and R23 multicore scores all beat the i5-4570R by margins between 4.3% and 4.4%, which makes it the better choice for CPU-bound rendering tasks like video encoding or 3D scene compilation. The single-core Cinebench results reinforce this, with the i5-6500T leading by 5.3% in R15 and 4.6% in R20, indicating that everyday applications with lighter threading requirements, such as web browsing or office productivity, would favor the newer chip.

The i5-4570R's only win comes in Geekbench multicore, where it posts 2872 against 2843. That 1% advantage is small, but it shows that the older Haswell design can still hold its own in certain parallel workloads, particularly those that respond to the specific scheduling and memory patterns of the Crystal Well architecture. For users running mixed multi-threaded applications that resemble Geekbench's workload mix, the i5-4570R offers a marginal edge, though the difference is unlikely to be perceptible in real-world use.

For single-core Geekbench, the i5-6500T's 7.2% lead (1016 versus 943) is the largest margin in the entire comparison. This is a meaningful gap for applications that rely heavily on a single thread, such as legacy games or script-heavy environments. The overall picture is that the i5-6500T is the stronger processor in nearly every scenario, with the i5-4570R's lone Geekbench multicore victory representing a niche outcome rather than a general trend.

Specification Differences

The two processors share the same core and thread counts, both offering 4 cores and 4 threads. Both also have identical L1 cache (64 KB per core) and L2 cache (256 KB per core), and neither supports ECC memory. Both use PCIe Gen 3 with 16 lanes (CPU only), and neither has an unlocked multiplier.

The key differences begin with clock speeds. The i5-4570R has a base clock of 2.70 GHz and a boost clock of 3.20 GHz. The i5-6500T runs at 2.50 GHz base and 3.10 GHz boost, meaning the Haswell part actually has higher clock speeds on paper, yet it still loses most benchmarks, which points to architectural efficiency gains in Skylake. The thermal design power differs significantly: the i5-4570R is rated at 65W, while the i5-6500T draws only 35W. That makes the i5-6500T substantially more power-efficient per unit of performance.

Memory support also diverges. The i5-4570R supports only DDR3, with dual-channel memory and a bandwidth of 25.6 GB/s. The i5-6500T supports both DDR3 and DDR4, also dual-channel, but with a higher memory bandwidth of 34.1 GB/s. The socket is another major split: the i5-4570R uses Intel BGA 1364 (a soldered, non-upgradeable package), while the i5-6500T uses Intel Socket 1151, which allows for socketed installation and potential future upgrades. The integrated graphics differ, with the i5-4570R featuring Iris Pro 5200 and the i5-6500T featuring HD Graphics 530, though the benchmark data does not assess GPU performance.

Architecture Differences

The i5-4570R is built on the Haswell architecture with the codename Crystal Well, while the i5-6500T uses the Skylake architecture with the same codename. These represent different generations of Intel's core design, and the manufacturing process reflects that: the i5-4570R uses a 22 nm node, while the i5-6500T uses a smaller 14 nm node. The die size tells the story of integration: the i5-4570R has a die size of 260 mm² and contains 1,700 million transistors, while the i5-6500T has a much smaller die at 122 mm², though the transistor count is not recorded in the database.

The cache hierarchy differs in the shared L3 cache. The i5-4570R has 4 MB of shared L3, while the i5-6500T offers 6 MB of shared L3. That 50% increase in L3 capacity likely contributes to the newer chip's better performance in memory-sensitive workloads, despite its lower clock speeds. The L1 and L2 caches are identical at 64 KB and 256 KB per core respectively.

The release dates place these chips about two years apart. The i5-4570R was released in June 2013, while the i5-6500T followed in July 2015. Both are now end-of-life products. The manufacturing foundry is Intel for both, as expected for these desktop parts. The market segment for each is listed as Desktop, although the i5-4570R's BGA socket indicates a soldered, embedded-style form factor, while the i5-6500T's Socket 1151 is typical of standard desktop motherboards. The process node shrink from 22 nm to 14 nm, combined with the architectural improvements in Skylake, explains why the i5-6500T achieves better performance with a lower TDP of 35W versus 65W, and why its memory bandwidth is higher at 34.1 GB/s versus 25.6 GB/s.
