The next generation of Intel Core processors, called Alder Lake, will be released this fall. Several benchmarks of the new processors have been made publicly available. The benchmarks include a 16-core desktop processor and a 14-core mobile processor. The leaks show that these new processors could bring a noticeable performance boost.
While there are several Alder Lake processors currently being tested, the latest leaks show the performance of one desktop and one mobile processor. It has been confirmed that the desktop processors will require the LGA 1700 socket, while the mobile Alder Lake processors will use the FCBGA 1744 socket. Both processors tested are equipped with Intel’s next-generation Xe graphics architectures.
The desktop variant has 16 cores and 24 threads. The model shown in the benchmark is probably one of the top models Intel is going to offer, with eight Golden Cove cores and eight Gracemont cores with 30MB of L3 cache. The base clock speed of the new Intel Alder Lake desktop chip will be 1.80 GHz, but due to an error in the leaked benchmarks, we don’t know the maximum clock speed yet.
This version of the processor includes the next-generation Xe-LP graphics card, which has 32 execution units (EU). The Xe-LP also has 256 cores with a clock speed of 1500 MHz. In one benchmark, the new Intel Alder Lake graphics were tested against the UHD 750 iGPU Rocket Lake. This comparison showed a definite increase in performance – Alder Lake scored 8,647 points compared to the UHD 750’s 7,974 points, a gain of about 8.5%.
It’s worth noting that these numbers may change in future benchmarks. The iGPU clock speed on Intel Alder Lake is 200 MHz higher than on Rocket Lake, so a boost is to be expected. However, there are no dedicated drivers for Alder Lake yet, so this may affect benchmark results. The final release may bring a performance gain of up to 10%, although it may be a bit lower than the current result of 8.5%.
As for the mobile version of Intel Alder Lake, the benchmark uses the Alder Lake-P ES chip with a 14-core, 20-thread combination. The core configuration will include six Golden Cove cores and eight Gracemont cores. The clock frequencies that have been made public are not yet final, but current estimates put the base clock frequency at 800 MHz with overclocking up to 4.0 GHz.
The mobile version of the chip has 24 MB of L3 cache and also comes with an Intel UHD Xe-LP graphics card. It is not yet clear whether this card is an integrated model or a discrete GPU. What is known, however, is that it has 96 EU, 768 cores, 1.5 GB of memory and a clock speed of up to 1200 MHz.
A comparison of mobile and desktop chips yields interesting results. Intel’s Alder Lake P, which is a mobile chip, scores 6,516 points in the OpenCL benchmark. This may seem surprising, considering the fact that the mobile graphics chip has more than twice as many cores. One reason for this relatively low score could be the lack of optimized drivers for the mobile processor.
Intel has said that Alder Lake, Intel’s 12th generation processor, will be released this fall. As the launch approaches, new benchmarks are likely to come out that will hopefully show a broader range of future Intel Alder Lake processors.
