Overview of the Products
When comparing the HP FAST EliteDesk 800 G3 SFF PC - Intel Core i7 6th Gen and the Intel Core i9-9900KF 3.6 GHz Eight-Core Processor, it's clear that they cater to different market segments. The HP desktop, priced at £139.99, offers a complete computing solution, while the Intel processor is a high-performance component priced at £265.00.
The EliteDesk is a refurbished unit designed for productivity in office or home environments, featuring an Intel Core i7 6th Gen processor, which provides adequate power for everyday tasks. In contrast, the i9-9900KF is a powerful processor that promises superior performance, particularly for demanding applications such as gaming or content creation.
Performance Analysis
In terms of raw performance, the Intel Core i9-9900KF outshines the i7 6th Gen processor. The i9 boasts 8 cores and 16 threads compared to the i7's 4 cores, which allows for significantly better multitasking and processing capabilities. The i9 can reach a maximum turbo frequency of 5.0 GHz, providing a higher peak performance compared to the i7's top speed of 4.00 GHz.
While the HP EliteDesk offers a solid experience for general use, the Intel processor is designed for those who need advanced processing power. This makes the i9 a better choice for gamers or professionals who run complex software, showcasing its superiority in performance metrics.
Memory and Storage Options
The HP FAST EliteDesk comes with 16GB of DDR3 RAM, which is ample for running multiple applications without lag. It also offers a choice between 512GB or 1TB SSD storage, ensuring fast boot times and quick access to files. This is particularly advantageous for users who require speed and efficiency for everyday tasks.
On the other hand, the Intel Core i9-9900KF does not include built-in memory or storage, as it is merely a processor. However, it supports dual-channel DDR4-2666 memory, which is generally faster than DDR3. Users looking to build a system around the i9 would need to invest in compatible memory and storage separately, potentially increasing the overall cost.
Connectivity Features
The HP FAST EliteDesk is equipped with a 150Mbps USB WiFi Adapter Dongle, allowing for reliable wireless connectivity. This feature makes it suitable for users who require a stable internet connection for remote work or online activities without the need for additional hardware.
Conversely, the Intel Core i9-9900KF does not have built-in connectivity features since it is a CPU. Users will need to ensure that their chosen motherboard includes the necessary networking capabilities. This could complicate the setup process for those unfamiliar with PC building, making the EliteDesk a more user-friendly choice for many.
Operating System and Software
The HP FAST EliteDesk runs on Windows 11 Pro, which provides users with the latest features and security enhancements from Microsoft. This modern operating system is optimised for productivity, offering a user-friendly interface and enhanced productivity tools that benefit professionals and casual users alike.
In contrast, the Intel Core i9-9900KF does not come with an operating system. Users must install their preferred OS, which may require technical knowledge and additional time. For those who wish to hit the ground running, the pre-installed Windows 11 Pro on the EliteDesk is a significant advantage.
Form Factor and Design
The HP FAST EliteDesk is designed as a small form factor (SFF) PC, which helps save desk space while delivering full desktop performance. Its compact design makes it an attractive option for users with limited workspace, whether in an office or home setting.
In comparison, the Intel Core i9-9900KF is a standalone processor that requires a compatible motherboard and additional components to function. This means that users will need to consider the overall size of their custom-built PC case, which may not be as space-efficient as the EliteDesk.
Price Consideration
At £139.99, the HP FAST EliteDesk offers an affordable option for users seeking a complete desktop solution. Its pricing is appealing for those who need a reliable PC without the need for extensive upgrades or custom builds.
Meanwhile, the Intel Core i9-9900KF is priced at £265.00, reflecting its higher performance capabilities. However, this price does not include the costs of additional components such as memory, storage, and a compatible motherboard. For budget-conscious consumers, the EliteDesk presents a more cost-effective solution for everyday tasks.
Which should you buy?
Choosing between the HP FAST EliteDesk 800 G3 SFF PC - Intel Core i7 6th Gen and the Intel Core i9-9900KF depends on your specific needs and budget. If you require a ready-to-use desktop solution that excels in general productivity and offers a good balance of performance and price, the EliteDesk is the better choice. However, if you are a power user who demands the highest processing capabilities for gaming, content creation, or intensive multitasking, the i9-9900KF is worth the investment despite the additional components required.
