Intel Core i7-8650U vs Intel Core i7-1195G7

Intel Core i7-8650U

The Intel Core i7-8650U is a power efficient quad-core SoC for notebooks and Ultrabooks based on the Kaby Lake Refresh generation and was announced in August 2017. Contrary to its direct predecessor the Core i7-7600U, which were still dual-cores, the i7-8650U is equipped with four cores but at a lower base frequency of 1.9 GHz. The Turbo Boost can go up to 4,2 GHz and therefore also offer good short term single core speeds. The GPU is now named Intel UHD Graphics 620 but otherwise identical to the Intel HD Graphics 620. The integrated memory controller supports DDR4-2400 / LPDDR3-2133 and dual channel memory.

Architecture

Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.

Performance

According to Intel, the new quad core models are up to 40% faster than their dual core predecessors. Due to the reduced TDP and the same 14nm+ process, the long term performance and throttling behaviour will be interesting and depending on the laptop design. Therefore, the older 35 Watt quad-core models should be faster in applications that demand longer CPU loads. The performance however is highly depending on the TDP settings and cooling solution of the laptop. Especially, longer loads will show varying results in different laptops.

Graphics

The integrated Intel UHD Graphics 620 (Intel Gen 9.5) is untouched from the 8th Gen Kaby Lake chips. With fast dual-channel memory it can reach the performance of a dedicated GeForce 920M.

Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.

Power Consumption

The chip is manufactured in an improved 14nm process with FinFET transistors (14nm+), the same as the 7th Gen Kaby Lake processors. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.

Intel Core i7-1195G7

The Intel Core i7-1195G7 is a quad-core SoC from the Tiger Lake-UP3 product family designed for thin laptops and Ultrabooks that was introduced in 2021. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). The base clock (minimum) depends on the configured TDP and can range from 1.3 GHz (12 Watt TDP) up to 2.9 GHz (28 W). The Turbo on one core can reach up to 5 GHz (Turbo Boost 3.0). All cores can reach up to 4.6 GHz. The i7-1195G7 is part of the Tiger Lake UP3 refresh and is the fastest CPU of the Tiger-Lake U line.

Furthermore, Tiger Lake SoCs supports four lanes of PCIe 4, AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6E in the chip.

The 1195G7 integrates the Intel Iris Xe graphics adapter with 96 EUs clocked at 400 - 1400 MHz. The GPU and CPU can together use the 12 MB of L3 cache.

Performance

The average 1195G7 in our database matches the Intel Core i5-10300H in multi-thread performance while, perhaps surprisingly, lagging behind the AMD Ryzen 3 5300U. The makes the i7 a decent lower mid-range chip, as of early 2022. It'll run most apps with virtually no delays or slowdowns which is what the vast majority of users wants.

Thanks to its decent cooling solution and a long-term CPU power limit of slightly more than 30 W, the VAIO SX14 VJS144X0111K is among the fastest laptops built around the 1195G7 that we know of. It can be about 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i7 series chip has a default TDP of 12 W to 28 W, the expectation being that laptop makers will go for a higher value in exchange for higher performance. Either way, that's a tad too high to allow for passively cooled designs.

The i7-1195G7 is built with Intel's 3rd generation 10 nm process marketed as SuperFin for below average, as of early 2023, energy efficiency.
