The Lenovo Yoga C940 81Q90041US is a laptop PC that is equipped with 10th Gen Intel® Core™ i7-1065G7 mobile processor. It is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Ice -Lake-U generation. It features four Sunnycove processor cores with 8 threads because of HyperThreading technology. The processor has a clock rate of 1.3 GHz GHz with a Turbo Core of up to 3.9 GHz. It has three levels of cache memory from 192 KB to 8 MB level 3 cache memory with a power consumption of 15W, thus it is designed well for ultraportable laptops. The TDP can be configured from a TDP of 7.5 - 25 Watts. It has a PassMark rating of 8993 points. The performance of this processor is slightly better than Ryzen 5-3550H but quite slower than Ryzen 5-4500U. Overall, this is a fast and efficient processor.

The Graphics Card 
The Lenovo Yoga C940 81Q90041US comes equipped with an integrated GPU called Intel® Iris® Plus graphics. The integrated GPU in this processor has the biggest G7 variant with 64 CUs clocked at 300 - 1100 MHz. The Iris Plus G7 should be doubled as fast as the ancestors and can best the AMD Vega 10 GPU in the existing Ryzen APUs. The performance of this GPU should be somewhat over an AMD Radeon RX Vega 10 integrated GPU in the Ryzen 7 3000 series processors As an example, Intel presented an Intel Iris Plus G7 alongside a Ryzen 7 3700U both configured at 25 Watt TDP and the Iris Plus GPU was able to beat the Vega 10 marginally in all games. Contrasted to the preceding generation, Intel discourses around a 2x performance enhancement. In general, the GPU would be placed in the entry-level of dedicated GPUs like Nvidia GeForce MX150 and thus most suited for less demanding games like Fortnite, Rainbow 6 Siege, or Rocket League at decreased details.

 The Lenovo Yoga C940 81Q90041US Go has 16GB system memory for intense multitasking and gaming, the considerable high-bandwidth RAM is needed to easily run your games, photo and video-editing applications, as well as to run multiple programs and browser tabs all at once. Specifically, the laptop has LPDDR4X RAM to smoothly run your graphics-heavy PC games and video-editing applications. The biggest change in this type of RAM is the decrease in I/O voltage (VDDQ) by almost 50% (1.12 to 0.61 V) generating a noticeable power drop on both the memory and system sides of the bus. These reserves turned out to be required for applications even reflecting the extra cost to produce a new voltage I/O power supply in the system. The maximum data rate was enlarged from 3200 to 4266 Mbps by increasing termination and calibration options. Newer system PHY’s were fabricated to leverage these selections and deliver more deskewing on the system side. Systems also commenced making more use of periodic correction functions presented in LPDDR4. Regrettably, LPDDR4X is not backward compatible with LPDDR4. LPDDR4X gadgets are not necessitated to be matching with or endure higher LPDDR4 voltage on their I/O. Likewise, there is no stated way to query an LPDDR4 or LPDDR4X device to ascertain its type during the power-up sequence. This is not as bad as it seems since LPDDR memory devices are not a user or even technician replaceable once mounted by the company.
