Rò rỉ hiệu năng gaming “đáng thất vọng” của CPU Intel Core i9-11900K, AMD Ryzen 7 5800X vẫn vượt trội hơn hẳn.

CPU Intel Core i9-11900K sẽ là con chip đầu bảng của thế hệ 11 “Rocket Lake”, và vừa rồi có thông tin rò rỉ trên trang Bilibili của Trung Quốc là hiệu năng đơn nhân của nó được cải thiện rất nhiều so với thế hệ trước. Ngoài ra, Core i9-11900K còn được đem ra so sánh với AMD Ryzen 7 5800X và Ryzen 7 5700G – một trong những con CPU chưa được ra mắt.


Intel Core i9-11900K được trang bị nhân Cypress Cove, hứa hẹn sẽ mang đến những nâng cấp đáng giá sau hơn 6 năm trời “vắt sữa” Skylake. Nó sẽ có 8 nhân 16 luồng, xung nhịp cơ bản 3,5 GHz và xung nhịp boost là 5,2 GHz (đơn nhân) hoặc 4,8 GHz (toàn nhân). Khi kết hợp với tính năng Thermal Velocity Boost thì xung nhịp boost đơn nhân sẽ lên đến 5,3 GHz. Được biết Core i9-11900K có Power Level 1 là 125 W và Power Level 2 là 250 W.


Theo bài test thì con chip Core i9-11900K được chạy với bo mạch chủ Z590. Còn AMD Ryzen 7 5700G là phiên bản thử nghiệm (engineering sample). Cả AMD Ryzen 7 5700G và Ryzen 7 5800X đều chạy với tính năng PBO được bật, còn Core i9-11900K thì chạy với xung nhịp 5,2 GHz.





Theo những bài benchmark trên thì Core i9-11900K có hiệu năng cao hơn cả 2 con CPU AMD kia về hiệu năng đơn nhân lẫn đa nhân. Tuy nhiên, khi xét đến khía cạnh gaming thì lại có sự thay đổi. Dù có xung nhịp đến tận 5,2 GHz Intel Core i9-11900K vẫn không thể bì kịp Ryzen 7 5800X trong một vài tựa game.


Dù đây chỉ mới là thông tin rò rỉ và CPU cũng chưa ra mắt chính thức, có vẻ như chip Intel thế hệ 11 “Rocket Lake” vẫn chưa đủ mạnh để trở lại cuộc đua với AMD Ryzen 5000 series. Đó là chưa kể nếu AMD có kế hoạch hạ giá thành CPU vào giữa năm 2021 thì Intel sẽ còn gặp nhiều khó khăn hơn nữa.

Intel claims Core i9-11900K will offer 11% faster storage performance than Ryzen 9 5950X​


Intel claims Rocket Lake has faster storage performance than AMD Zen3​

Intel’s Chief Performance Strategist Ryan Shrout and Storage Technical Analyst Allyn Malventano, are claiming that the upcoming flagship Core i9-11900K processor from the Rocket Lake-S series will offer up to 11% faster storage performance on PC Mark 11 Quick System Drive Benchmark compared to AMD Ryzen 9 5950X. This is actually the first official benchmark of the new processor. The series is expected to launch next month, but the company has not yet confirmed the exact launch date, but the fact that Intel is already showing benchmarks, may further confirm that the launch is imminent.

The test features 1TB Samsung 980 PRO, which is PCI Gen4 compatible drive. According to Ryan Shrout’s tweets, the drive was attached to the PCIe riser, to ensure it is using CPU lanes as opposed to chipset lanes. In such a scenario, the i9-11900K is 11% faster than AMD Ryzen 5950X, which is the flagship “Vermeer” CPU based on Zen3 architecture.

AMD X570 motherboards were the first PCIe Gen4 capable platform from AMD. The company was expected to provide partial support on older motherboards, but the plans were eventually scrapped. On the other hand, Intel has launched its Z490 motherboard series last year with PCIe Gen4 hardware readiness for the 11th Gen Core series which would not launch until this year. Intel has not yet confirmed which Z490 motherboard will support the newer standard, but even if they do support it, it will be limited. Intel Rocket Lake-S CPUs are the first series to have dedicated CPU lanes for the PCIe Gen4 storage and this feature will be exclusive to Z590 chipsets.

Intel Core i5-11600KF and i5-11400F 6-core 12-thread Rocket Lake-S CPUs tested​


Intel Core i5-11600KF and Core i5-11400F tested​

A member of a Chiphell community has managed to get access to two unreleased 6-core Intel Rocket Lake-S CPUs.

Intel Rocket Lake-S has already been extensively tested by respected and known tech publications even before the company formally announced the new series. We have seen multiple reviews of Core i9-11900 series engineering samples weeks in advance, and more recently we get to see retail Core i7-11700K CPUs showing their muscles in reviews from AnandTech and HardwareLuxx.

All these CPUs were 8-core and 16-thread SKUs, which will probably become the most popular choice among Intel enthusiasts, but for people on a budget, the Core i5 series may still be a better deal. On Chiphell, a short review of two 6-core and 12-thread Core i5 CPUs can be found. The member of this community gained access to Core i5-11600KF (unlocked CPU without integrated graphics) and Core i5-11400F (also lacking onboard graphics).

The 11600KF has a TDP of 125W and can boost up to 4.9 GHz and it has a base clock of 3.9 GHz, that’s according to the CPU-Z. The 11400F, on the other hand, is a 65W model with a base clock of 2.6 GHz and a max turbo clock going up to 4.4 GHz. Both are based on Cypress Cove architecture and will offer PCI Gen4 support. Unfortunately, both being part of the F-series will lack integrated Xe Gen12 graphics.

The CPUs were tested on Gigabyte Z490 AORUS Ultra motherboard which featured the latest available BIOS for the 11th Gen Core series. This does not mean that Gigabyte will not release even more optimized BIOS before launch, and we have already seen that there still a lot to gain from the newer microcode. The system was paired with 16GB of ZADAK Spark DDR4-3600.

Both CPUs were cooled down by a triple-fan AIO kit called ‘GI-CX360 ARGB’ by PCCooler. The cooling is rated at a maximum of 350W. More than enough for these Core i5 CPUs, even in their PL2 power states. Under load in the AIDA64 test, the 11600KF has an average of 209W power consumption and a temperature of 85C. The 11400F on the other hand reported an average of 145W and 70C.

The reviewer notes that there may still be changes to performance once a newer BIOS will be released. He tested overclocking on i5-11600KF but the results were underwhelming. He notes that the limit is 4.8 GHz and 4.9 GHz with 1.4V applied, but it was unstable. The temperature has increased noticeably as well, so eventually, he gave up. The 11400F being a non-K part obviously cannot be overclocked, but there are tricks with PL2 and Tau modifications, which the reviewer did not test. Gaming tests were not performed, because the user expects better optimization with newer BIOS.
