Intel Pentium 8505 vs Intel Core i3-1210U vs Intel Core i7-1255U

Intel Pentium 8505

► remove from comparison Intel Pentium 8505

The Intel Pentium 8505 is an entry-level mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers one performance core (P-cores, Golden Cove architecture) and 4 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 6 supported threads when combined with the E-cores. The clock rate ranges from 1.2 to 4.4 GHz on the performance cluster and 0.9 to 3.3 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 8 MB L3-cache. Compared to the faster Core i3-1215U, the Pentium offers one less P-core.

Performance

This is a fairly unpopular CPU, if the fact that we have not tested a single system built around it as of August 2023 is any indication. That said, we have tested a few systems featuring the Core i3-1215U, a chip with the same clock speeds and the same 4 E-cores but with 2 P-cores instead of 1. Based on that, expect the 8505 to be 10% to 20% behind the Ryzen 3 5300U and the Core i7-1185G7, as far as multi-thread benchmark scores are concerned.

Your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.

Features

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics adapter is based on the Xe-architecture and offers 48 of the 96 EUs (Execution Units) operating at up to 1.1 GHz.

Power consumption

The Pentium has a Base power consumption of 15 W, with 55 W being its maximum Intel-recommended Turbo power consumption. These values are fairly high; passive cooling solutions aren't really an option here.

The CPU is built with Intel's 3rd generation 10 nm process marketed as Intel 7 for decent, as of early 2023, energy efficiency.

Intel Core i3-1210U

► remove from comparison Intel i3-1210U

The Intel Core i3-1210U is a low power mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 2 performance cores (P-cores, Golden Cove architecture) and 4 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 8 supported threads when combined with the E-cores. The clock rate ranges from 1 to 4.4 GHz on the performance cluster and 0.7 to 3.3 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 10 MB L3 cache. 

Performance

While we have not tested a single system built around the 1210U as of August 2023, we fully expect its multi-thread performance to be pretty much identical to that of the i3-1215U. Which is pretty fast for an entry-level chip, as of mid 2023.

The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics adapter is based on the Xe-architecture and offers 64 of the 96 EUs (Execution Units) operating at up to 0.9 GHz.

Power consumption

This Core i3 has a Base power consumption of 9 W, with 29 W being its maximum Intel-recommended Turbo power consumption. TDP values that low allow for passively designs as long as performance is not a priority.

The CPU is built with Intel's 3rd generation 10 nm process marketed as Intel 7 for decent, as of early 2023, energy efficiency.

Intel Core i7-1255U

► remove from comparison Intel i7-1255U

The Intel Core i7-1255U is a high-end mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 2  performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 1.7 to 4.7 GHz on the performance cluster and 1.2 to 3.5 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 12 MB L3 cache. Compared to the i7-1265U (fastest U-series CPU at launch), the 1255 offers 100 MHz lower clocked CPU cores and only "Essentials" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.

Performance

The average 1255U in our database is in the same league as the Ryzen 5 5600U, as far as multi-thread benchmark scores are concerned. Which is nothing to be ashamed of, as of mid 2023.

Thanks to its decent cooling solution and a long-term CPU power limit of 28 W, the Spectre x360 13.5 14t-ef000 is among the fastest laptops built around the 1255U that we know of. It can be 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Architecture

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance.

The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics card is based on the Xe-architecture and offers all 96 EUs (Execution Units) operating at up to 1.25 GHz.

Power consumption

This Core i7 has a "minimum assured" power consumption of 12 W. Its Base power consumption sits at 15 W and its maximum Intel-recommended Turbo power consumption isn't supposed to exceed 55 W. All those values are too high to allow for pasisvely cooled designs.

Last but not the least, Core i7-1255U is built with Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency.
