Đánh giá intel core i7 7800x năm 2024

Following half a decade or more of dominance at the top of the calm seas of CPU performance leagues, Intel is once again facing imminent competition in the High End Desktop Market. This week�s launch of the new Core-X CPUs and X299 platform is a pre-emptive salvo across the bows of AMD�s Threadripper dreadnought, seeking not only to win the battle before the new CPU can get out of dry-dock but also firmly supplant their own ageing Broadwell-E fleet. The question is, do they have what it takes to stave off the competition?

We already had opportunity to review the new Kaby Lake-X Core i7-7740X on the X299 platform, and in fairness failed to be blown away. As a product they are broadly similar to the mainstream i7-7700K in price, performance and features; as a result they�re difficult to justify on a more expensive platform. One slight ray of sunshine was improved overclocking versus the 7700K, but we shouldn�t generalise one engineering sample to be representative of the entire retail production run in this instance.

The entire launch range for Intel's Core X CPUs is something of a mixed bag, and that's without even considering the 12-18-core models anticipated later this summer. Two distinct CPU architectures, four different core counts, PCI-Express lanes supplied and of course price separate all the models, which will make choosing which CPU to opt for all the more difficult.

Today we�re looking at a retail version of the first Skylake-X CPU in Intel�s Core X range, the Core i7-7800X. An abridged feature list clearly indicates that it is a far different beast to the 7740K: six cores, twelve threads, quad-channel memory controller and a substantially revised CPU microarchitecture compared to the mainstream Skylake CPUs. Perhaps the most interesting aspect however is the price.

The Core i7-7800X is available right now at Overclockers.co.uk retailing at �379.99 for retail SKUs and �349.99 for OEM variants (the street price being especially relevant for new premium products). That places it only a hair more expensive than the Core i7-7740X, but with exactly the same motherboard selection and a far wider feature set. Direct comparisons between the two are therefore particularly relevant, even with AMD�s Threadripper CPUs not yet in the picture.

Intel started Core i7-7800X sales 26 June 2017 at a recommended price of $389. This is a Skylake (server) architecture desktop processor primarily aimed at office systems. It has 6 cores and 12 threads, and is based on 14 nm manufacturing technology, with a max turbo frequency of 4000 MHz and an unlocked multiplier.

Compatibility-wise, this is FCLGA2066 processor with a TDP of 140 Watt and a maximum temperature of 72 °C. It supports DDR4-2400 memory.

It provides poor benchmark performance at 8.43% of a leader's which is AMD Ryzen Threadripper PRO 7995WX.

Compatibility

Information on Core i7-7800X compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.
