Decent price, kept me updated with progress, well packed (and they chucked in some sweeties!) and good delivery. Great service overall.Read on Google
Intel Core i9 Processors are the most powerful mainstream CPUs available from Intel, with the 12th generation Alder Lake processors following this trend. The model was first introduced in 2017 as one step above their previous highest consumer-focused CPU, the Core i7 range. Generally speaking, these processors have up to 18 cores and double the number of threads. Alder Lake i9-12900K is equipped with 16 cores and 24 threads, but utilises innovative core technology to work with the greatest efficiency and cohesion. Thanks to this powerful architecture and Intel technologies, the Core i9 has outstanding multi-threading performance, making them the ideal processor for streaming, gaming, and content creation. When it comes to gaming, the Core i9 is capable of rendering even the most demanding AAA titles in 4K resolutions, creating an intensely immersive experience. Other models in this range are the Intel Core i3, i5, and i7, which provide entry to high-tier level performance.
As the top tier of the Intel Core range, i9 models boast the highest of cores/threads with the fastest clock speeds. With their amazing multi-threading capabilities, these processors are perfect for overclocked gaming and content creation. Whatever the workload, these processors can more than keep up!
With new generations come new innovations. The 12th generation of Intel’s Core processors are packed with their latest and greatest developments. Alongside incredible integration with Windows 11, these processors support the next-gen tech we’re expecting to see. This includes DDR5 and PCIe 5.0.
Additionally, these CPUs sport enhanced versions of Intel technologies we know and love. Intel Smart Cache has received a boost in performance, with the L3 and L2 caches facilitating larger capacities whilst reducing latency. The overall design of 12th Gen Intel Core CPUs has been primed for gaming, optimising your experience.
With twelfth generation Alder Lake intel, CPUs Intel introduced an entirely new core layout with Performance (P-core) and Efficient cores (E-core).
Optimising the performance from these cores, Intel developed Thread Director. Instead of the operating system reading data and assigning cores, this hardware features guides the process. Guesswork is taken out of task assignment, thanks to this, thus creating much more efficient workloads. This is functionality like no processor before.

Read MoreThe i9 series of processors are Intel’s top consumer range and one level above the i7 series. They offer higher core counts, clock speeds and professional productivity and overclocking features.
Both the i9 and i7 are designed for high-end performance. However, the i9 sports Intel's latest enthusiast features with higher core counts. What’s more, there is great potential with outstanding performance and efficient core design.
Intel’s twelfth generation Alder Lake i9-12900k CPU boasts 16 cores and 24 threads and is Intel’s most powerful consumer CPU. What’s more, 12th generation intel CPUs benefit from a new core design with both performance and efficiency-based cores.
That depends on the model. Some models do, but if you would rather opt for a dedicated graphics card then look for i9 models ending in F. Ie, Intel Core i9-12900KF. This denotes that there are no onboard graphics, and is true for all Intel Core processors.
Intel Core i9 processors that can be overclocked end in K, such as Intel Core i9-10900K. This indicates that they are unlocked and ready to overclock.
