Intel has officially announced their refreshed versions of the Tiger Lake-U 10nm CPUs, which include: Core i7-1195G7 and Core i5-1155G7. These processors will target the ultra-low-power laptop category.
Both the Intel Core i7-1195G7 & the Core i5-1155G7 are based on the 10nm SuperFin process node. The processors fall under the Tiger Lake-U family and are designed for laptops whose TDPs are in the range of 12-28W.
Intel Core i7-1195G7 Tiger Lake-U CPU Specifications:
The flagship processor comes with 4 cores and 8 threads. It also has a 12 MB Cache and supports DDR4-3200 / LPDDR4X-4266 memory. The processor maintains the TDP between 12-28W and operates at a base clock speed of 2.9 GHz, which can go up to 5.00 GHz on a single core and 4.60 GHz (all-core) boost. This makes the Tiger Lake-U the first ultra-low power chip to feature a 5.0 GHz boost clock speed. As for the graphics department, Xe-LP architecture is offered with 96 EUs /768 cores at 1.4 GHz clock speed.
Intel Core i5-1155G7 Tiger Lake-U CPU Specifications:
The Core i5-1155G7 also comes with 4 cores, 8 threads, and 8 MB of cache. The processor also supports DDR4-3200 / LPDDR4X-4266 memory and maintains the TDP at 12-28W. It operates at a base clock speed of 2.5 GHz base and can boost up to 4.30 GHz on all cores and 4.50 GHz on a single core. The Xe-LP architecture handles the graphics department with its 80 EUs/512 cores operating at 1.35 GHz clocks.
Some important things to note are that the stated TDP will be maintained when operating at base speeds. Once the processor approaches boost clock speeds, the TDP will increase. Moreover, Intel’s benchmarks for Tiger Lake-U parts show a 2.78x performance lead over AMD’s Ryzen 7 5800U (Cezanne-U) APU. However, the Ryzen 7 5800U has a TDP range of 15-25W while the TDP of Core i7-1195G7 lies in the range of 28-35W, giving it an advantage.
Intel is also promoting another key feature of its Xe graphics chip in comparison to Vega GPU, which is DX 12 sample feedback. Due to this, Intel witnesses a 2.34x performance gain than Vega GPU in the 3DMark Sampler Feedback test and a 2.0x gain with the feature disabled.
The i7-1195G7 has a lead in terms of content creation, and Intel claims a massive 8x lead in 10-bit video encoding through Intel Quick Sync Video acceleration. It also has more encode/decode options than the competition. The stated specification looks promising, but we will have to see how it performs in real-life scenarios.
