Intel has introduced a series of 11th-generation Tiger Lake mobile CPUs, based on the 10nm manufacturing process used in the 10th-gen Ice Lake. Intel has made a significant change with Tiger Lake by improving CPU core speed and has also introduced the long-awaited XE graphics engine. In addition, Tiger Lake has some baked-in features such as new-generation wireless connectivity and significantly improved Artificial Intelligence (AI) performance.

Pricing and availability
The additional performance at Tiger Lake is so significant that Intel took the unusual step of providing a small number of Tiger Lake laptops to reviewers in mid-September before its launch. At the time, we were allowed to post benchmark results to show the performance of the new CPU and GPU combo, but we were not allowed to discuss battery life, as those sample laptops were not fully configured for retail sale Were done.
The rollout of the 10th-gen Ice Lake CPU was slow and steady, and the same is true for the 11th-gen Tiger Lake. Currently, you can find very similarAnd On behalf of laptop sales. We have seen a steady release of new models in the early months of 2021, but you still need to make sure that you are buying the latest technology instead of last year’s model. There are various eight-gen laptops still on sale, so you need to pay full attention to the specification.
Intel Tiger Lake offers significant performance enhancements over Ice Lake in terms of both CPU and GPU, although pricing has been stable, with costs largely the same for individual CPUs in both generations.
Tiger Lake is based on an enhanced 10nm process node named 10nm SuperFIN. While there have been some improvements on Ice Lake at the architecture level, the key to Tiger Lake is in its willow cove core, which uses superfine transistors at lightning speeds that were out of reach for the Sunny Cove core found in the Ice CPU.
The new superfine transistors allow Willow Cove – and therefore, Tiger Lake – to run clockwise – which we are accustomed to seeing in gaming laptops, where Ice Lake was roughly below 1GHz. As depicted, the Ice Lake Core i7-1065G7 has a max turbo frequency of 3.90GHz, while the comparable Tiger Lake Core i7-1165G7 runs as fast as 4.70GHz.
This bump in clock speed has some fascinating consequences. When covered rumors about Tiger Lake before launch, we reported that an early engineering sample of the Tiger Lake Core i7-1185G7 was clocked at 3GHz (via) TUM APISAK) Belongs to. On UL’s 3DMark Time Spy benchmark, the CPU scored 1,414 points, and the breakdown showed that the quad-core chipset scored 1,296 points on the graphics test and 2,922 on the processor test.
It was an exciting early indicator of his abilities, but it turned out that Tiger Lake could go much further.
As this Scrangrab shows, the performance of those preview numbers makes sense given the performance you can see from Intel Tiger Lake. The explanation is that Tiger Lake can run at 3.6GHz on all cores under constant load, provided you feed enough power to it. This adds an important variable to any performance statistics you see for Tiger Lake, as you have to understand the power settings before you can understand the test result.
In post-release testing, Tiger Lake CPU demonstrated solid single-core test results in the Cinebench R20. In it, the Intel Ice Lake and AMD Ryzen 7 4800U CPUs have been crushed by the new Intel Tiger Lake, while in the multi-core test, AMD is ready to win again. You’ll note that AMD has eight cores against Intel’s four cores, so it’s no surprise that AMD wins. However, Intel is using slightly more power than AMD to close the Tiger Lake gap.
In preview laptops, the Intel Tiger was set to 28W in balanced mode and 41.5W in high-performance mode, which is bold considering the Core i7-1185G7, with a TDP-up of 28W and a TDP of 12W. -down occurs. In other words, you can buy a new thin and light Tiger Lake laptop with TDP, configured at a fraction of the power used in the benchmark shown above, and this will result in the raw performance that Intel Ice Lake has are equal.
On the other hand, if you are running workloads using new features in Tiger Lake, such as the newly-supported AVX-512 instruction set, you can expect specific tasks to speed up. This instruction set was previously only available in Intel’s Xeon and Skylake-X processors, so we’re in new territory when it comes to thin and light laptops. The demo we’ve seen that uses the AI features in Tiger Lake exponentially enhances photos, with crippling resolution and detail for the machine’s learning power. This obviously depends on software support and is a situation that will develop throughout 2021.
Tiger Lake brings a significant improvement in CPU performance over its predecessors, though the more impressive Generation Leap comes in the form of its 12th-generation X graphics. Tiger Lake is the first generation of Intel CPUs to take advantage of Intel’s new X graphics architecture, the Grander version that will power Intel’s upcoming dedicated graphics card.
Intel is offering vast performance improvements with the Xe, but this is dependent on the model of processor in your new laptop and the configuration set by the laptop manufacturer. The best-case scenario is an 11th-gen Core i7 with G7 graphics that sports 96 execution units that give a 50% bump on the best graphics in Intel’s Ice Lake line-up. Integrated graphics systems rely on memory so Intel has pushed the limits with memory support for Tiger Lake. The fastest Tiger Lake laptops use LPDDR4x-4266 memory, which helps the CPU and also provides a significant boost to graphics.
Intel Iris Xe graphics provide sufficient performance at 60 fps for 1080p gaming in e-sports titles and older AAA games, though Nvidia graphics such as the GeForce MX350 put up a fair fight and we have every hope that the new NVIDIA GeForce MX450 is a good one. The match will be for Tiger Lake.
Intel graphics are generally considered weak and have little use for gamers. The new XE graphics are definitely a step forward for gamers, although Intel is offering a bigger picture with its CES claims of “the most disruptive and advanced architecture”. In September we saw several stories about new features such as display state buffers, which reduced loading time and CPU usage, freeing up CPU for other activities and overall performance. We’ll be interested to see how this plays out when the feature lands in Windows 10, but right now Xe delivers 50% more performance units running at higher speeds and with much faster memory, and this is a winning formula. is.
Wi-Fi, AI, and more
Two big enhancements eager to talk about Intel with Tiger Lake are how it will affect wireless networking and AI development. We’ll have to wait and see how AI benefits, because it will obviously take time. While we may see faster performance at some workloads, disabling AI features seems impossible, so we are unlikely to be able to divine the exact benefits of AI in Tiger Lake.
For Wi-Fi, the sixth generation (802.11.ax) is supported natively by Tiger Lake, allowing users high-speed data transfer, improved performance on busy networks, improved latency and reduced power draw. . This is the same for Tiger Lake devices for improved connection speeds and longer battery life, as we have already seen with Ice Lake. What’s new is “the latest generation of display technology”, so you can expect both HDMI 2.1 and Thunderbolt 4 on premium Tiger Lake laptops.
the dark shadow
Intel’s Ice Lake CPU included the largest collection of hardware fixes for mainstream processors seen from Intel, and we fully expected Tiger Lake to improve with additional security features on it. It is clear that Intel has made changes, however, details have not been made public. Takeaway feels that Tiger Lake is more flexible than earlier CPUs and disabling these changes actually hurts performance. In other words, you do not need to choose between security or performance, but instead run Tiger Lake by default.
