Even with DDR4-3200 system memory, it's a very strong showing for AMD. What happens when you take an already-strong floating-point unit design, and make it even stronger? Here's your answer.
CINEBENCH 15 UPDATE
Iris Xe G7 96EUs 1250 / 2133 MHz Chrome 105.0.0.'Zen 2' Ryzen 7 and Ryzen 9 Update (July 12, 2019)ĪMD's brand-new third-generation Ryzen processors have now been released, which means it's time to update these graphs once again.
Intel Iris Xe Graphics G7 96EUs ( - 1250 MHz) Power Consumption (TDP = Thermal Design Power) Series: Alder Lake-M Alder Lake-U Intel Core i7-1265U Last but not the least, Core i7-1255U is built with Intel's third-gen 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency. All those values are too high to allow for pasisvely cooled designs. Its Base power consumption sits at 15 W and its maximum Intel-recommended Turbo power consumption isn't supposed to exceed 55 W. This Core i7 has a "minimum assured" power consumption of 12 W. The integrated graphics card is based on the Xe-architecture and offers all 96 EUs (Execution Units) operating at up to 1.25 GHz. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs). 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. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). 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 integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. Thanks to the architectural improvements of the big Golden Cove cores, the single thread performance should be better than similar clocked Tiger Lake CPUs. The sustained performance will be limited by the TDP setting and thermals and therefore only short term loads. Thanks to the 10 cores, the multi-threaded performance should be clearly faster than the older quad-core Tiger Lake CPUs with 15 Watt (like the Intel Core i7-1160G7).
Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance. 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. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). 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 P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. 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 Intel Core i7-1255U is a high-end mobile CPU for thin and light laptops based on the Alder Lake architecture.
