Intel Core i5-4570T vs Intel Pentium 6805 Comparison

The Intel Core i5-4570T and the Intel Pentium 6805 are two very different processors that happen to share a core count and thread count. The i5-4570T is a 2013 desktop part built on a 22 nm Haswell design, while the Pentium 6805 is a 2020 mobile processor on the 10 nm Ice Lake-Y architecture. Both have 2 cores and 4 threads, and both land at the 31st percentile of all CPUs in the database, which means they perform in the same general tier. However, the benchmark scores show a clear and consistent gap, with the Pentium 6805 winning every single head-to-head test by a margin of roughly 28%. The data paints a picture of an older desktop chip being outclassed by a newer, more efficient mobile chip in raw compute tasks.

Where Each One Wins

The Intel Pentium 6805 wins in every benchmark category recorded, so the main question is not where it wins, but by how much and in what workloads. In Cinebench R15 multicore, the Pentium 6805 scores 383 against the i5-4570T’s 275, a 28.2% advantage. That trend continues in Cinebench R20 multicore, where the Pentium 6805 posts 1596 versus 1147, a 28.1% lead. For single-core performance, the Pentium 6805 also dominates: 225 versus 161 in Cinebench R20 single-core (28.4% ahead) and 536 versus 385 in Cinebench R23 single-core (28.2% ahead). The largest absolute gap is in Cinebench R23 multicore, where the Pentium 6805 scores 3801 compared to 2732, again 28.1% higher.

There is no test in the database where the i5-4570T comes out ahead. The wins for the Pentium 6805 are consistent across both single-threaded and multi-threaded workloads, which suggests that the architectural improvements in Ice Lake, such as a newer process node and a higher IPC design, benefit all types of tasks. For a user deciding between these two, the Pentium 6805 is the clear choice for any compute-heavy application, from video encoding to software compilation, as long as the system can accommodate its BGA 1526 socket and mobile form factor.

The i5-4570T’s only advantage lies in its platform characteristics, not its raw performance. It uses the Intel Socket 1150, which means it can be installed in a wide range of older desktop motherboards. It has a 35 W TDP, which, while higher than the Pentium 6805’s 15 W, is still low enough for compact desktop builds. The i5-4570T also supports DDR3 memory, which is an older but widely available standard. However, these are platform advantages, not performance wins. In terms of benchmark scores, the i5-4570T has zero wins out of five head-to-head tests. The data is unambiguous: the Pentium 6805 is the faster processor in every measured scenario.

Architecture Differences

The two chips come from completely different eras and design philosophies. The i5-4570T is based on the Haswell architecture, using a 22 nm process node from Intel. It has 1,400 million transistors on a die size of 177 mm². In contrast, the Pentium 6805 uses the Ice Lake architecture with the Sunny Cove-Y microarchitecture, built on a 10 nm process node, with a die size of 123 mm². The smaller die and newer node mean the Pentium 6805 is significantly more efficient in terms of performance per watt, which is reflected in its 15 W TDP against the i5-4570T’s 35 W TDP.

Cache layouts differ as well. The i5-4570T has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 4 MB of shared L3 cache. The Pentium 6805 has a larger L1 cache at 80 KB per core, the same 256 KB of L2 per core, and an identical 4 MB of shared L3 cache. The larger L1 cache on the Pentium 6805 is a sign of the newer architecture’s focus on improving single-thread performance, which shows up in the single-core benchmark scores.

Memory support is another major difference. The i5-4570T uses DDR3 memory with a dual-channel bus, while the Pentium 6805 supports DDR4 with a dual-channel bus and a recorded memory bandwidth of 51.2 GB/s. The Pentium 6805 also has a socket of Intel BGA 1526, which is a soldered mobile package, whereas the i5-4570T uses the socketed Intel Socket 1150. Both chips use PCIe Gen 3, but the i5-4570T is a desktop part with an integrated Intel HD 4600 GPU, while the Pentium 6805 has UHD Graphics with 32 execution units.

The base and boost clocks tell an interesting story. The i5-4570T has a base clock of 2.90 GHz and a boost clock of 3.60 GHz. The Pentium 6805 has a base clock of 1100.00 MHz (1.10 GHz) and a boost clock of 3.00 GHz. The i5-4570T has a higher base clock, but the Pentium 6805’s boost clock is only 0.6 GHz lower. Despite the lower base clock, the Pentium 6805 outperforms the i5-4570T in all tests, which indicates that the Ice Lake architecture’s instructions per clock (IPC) advantage is substantial. The Pentium 6805’s boost clock of 3.00 GHz is enough to overcome the i5-4570T’s higher base and boost speeds. The release dates confirm the generational gap: the i5-4570T was released in June 2013, while the Pentium 6805 came out in September 2020.

The Verdict

Based strictly on the recorded data, the Intel Pentium 6805 is the superior processor. It wins all five head-to-head benchmarks with a consistent delta of about 28.2% in its favor. The average benchmark score for the Pentium 6805 is 1099, while the i5-4570T sits at 1108, a difference of less than 1%, but that average includes the i5-4570T’s Geekbench scores, which are not present for the Pentium 6805 in the same test set. Looking at the shared Cinebench tests, the Pentium 6805 is clearly ahead. The i5-4570T’s nearest rivals include the AMD PRO A12-8870 and AMD Opteron 4280, both with average scores around 1107, while the Pentium 6805’s nearest rivals include the Intel Core i5-3450S and Intel Pentium Gold G6500, with scores around 1099 to 1101. This puts both chips in a similar overall performance class, but the Pentium 6805’s wins in every direct comparison make it the better choice for compute tasks.

The i5-4570T should only be chosen if the user specifically needs a socketed desktop processor for an older LGA 1150 motherboard. It has a higher base clock, but that does not translate into better benchmark results. The Pentium 6805, despite being a mobile part with a lower base clock, delivers 28% better performance in Cinebench tests. For anyone building a new system or upgrading, the Pentium 6805 is the faster part. The i5-4570T’s only real advantage is its platform compatibility with older desktop boards, which is a hardware ecosystem consideration, not a performance one. The data shows no scenario where the i5-4570T wins a benchmark, so the verdict is straightforward: the Pentium 6805 is the better processor in terms of raw performance.

Head-to-Head Benchmarks

The head-to-head data is decisive. In Cinebench R15 multicore, the Pentium 6805 scores 383 against the i5-4570T’s 275, a 28.2% difference. That is the smallest gap in absolute points, but the percentage is consistent with the other tests. In Cinebench R20 multicore, the Pentium 6805 reaches 1596, while the i5-4570T manages 1147, a 28.1% lead. The multicore scores show that the Pentium 6805’s advantage holds even when both cores are fully loaded, which is notable given the i5-4570T’s higher base clock of 2.90 GHz versus the Pentium 6805’s 1.10 GHz base.

Single-core benchmarks follow the same pattern. Cinebench R20 single-core gives the Pentium 6805 a score of 225 versus 161 for the i5-4570T, a 28.4% gap. Cinebench R23 single-core shows the Pentium 6805 at 536 and the i5-4570T at 385, a 28.2% difference. These single-core results are particularly important because they indicate that the Pentium 6805’s architectural efficiency, not just its ability to use multiple threads, drives the performance advantage. The Ice Lake architecture’s larger L1 cache (80 KB per core versus 64 KB per core) and newer 10 nm process likely contribute to this.

The largest absolute win for the Pentium 6805 is in Cinebench R23 multicore, where it scores 3801 versus 2732. That is a difference of 1069 points, or 28.1%. The i5-4570T’s best showing is in Geekbench multicore, where it scores 2016, and Geekbench single-core, where it scores 1042, but the Pentium 6805 does not have Geekbench scores in the database, so no direct comparison is possible there. In every test where both chips have recorded scores, the Pentium 6805 wins by a nearly identical margin of about 28%. This consistency suggests that the performance gap is due to fundamental architectural improvements rather than workload-specific optimizations.

The i5-4570T’s average benchmark score is 1108, while the Pentium 6805’s is 1099. This is a negligible difference of less than 1%, but it is skewed by the fact that the i5-4570T has Geekbench scores included in its average, while the Pentium 6805 does not. When comparing only the shared Cinebench tests, the Pentium 6805 is clearly superior. The i5-4570T’s nearest rivals, such as the AMD PRO A12-8870 with an average score of 1107, are comparable to its own score. The Pentium 6805’s nearest rivals, including the Intel Core i5-3450S at 1099 and the Intel Pentium Gold G6500 at 1101, are also in the same range. Both processors sit at the 31st percentile of all CPUs, meaning they are not top-tier parts, but within their class, the Pentium 6805 is the stronger performer.

Specification Differences

The two processors differ in nearly every specification that matters. The i5-4570T uses the Haswell architecture on a 22 nm process, with a die size of 177 mm² and 1,400 million transistors.
