# Intel Xeon 6990E+ Server CPU: Intel Also called intel xeon 6990e+, xeon 6990e+, 6990e+, xeon-6990e+ Intel, Server CPU, Clearwater Forest Intel Xeon 6 server processor on Clearwater Forest, with 288 cores and 288 threads and 576 MB L3 at 450 W TDP addressing up to 1.5 GB and no integrated graphics. ## What you need to know Still a capable Xeon 6 desktop chip. Intel Xeon 6990E+ launched in April 1, 2026., It has 288 cores and 288 threads on Clearwater Forest, dropping into the FCLGA7529 socket. It is no longer the newest SKU in every store, but the chip is still useful when the rest of the PC keeps up. - **Still good?**: Yes, for most work this class is sold for **Product age**: Less than a year old **Upgrade pressure**: Low Feex says This SKU has no picture of its own. If the machine has no discrete GPU, a black screen after install is expected, not a dead CPU. ## What this hardware means today Age and usefulness are not the same number. This page keeps them separate. - **Performance today**: **Excellent.** Excellent for the class when RAM, storage, and the GPU keep up. **Product age 0 years old**: **Current generation.** Launched April 1, 2026. Newer platforms exist. That does not make this chip unusable by itself. **Support status **: **Supported.** Current Windows and current applications still run on this class of CPU. Platform BIOS support depends on the motherboard or laptop vendor. **Upgrade pressure **: **Low.** Upgrade pressure is low unless you need a different platform feature. ## Where does it sit? Clearwater Forest sits on Intel's recent Core timeline. Later desktop branding moved toward Core Ultra. 11th Gen 12th Gen 13th Gen 14th Gen Core Ultra ## Performance context These are qualitative readings, not a fake 8.7 out of 10. Workload still wins. ### Gaming: Poor fit Not the job. Use a desktop or workstation part if games are the point. ### Productivity: Excellent 288 cores cover office, browser, and compile work in this class. ### Multithreaded workloads: Very Good 288 threads. Heavy encodes still scale further on higher-core parts. ### General use: Excellent Everyday Windows use is not where most people notice this SKU first. ### Efficiency: Average Rated 450 W base power. That is a platform number, not a promise about your cooler. ## Should you upgrade? Probably not if this chip already matches your work. ### Upgrade makes more sense if - Your workload is strongly CPU limited - You need a newer platform for memory, I/O, or chipset features - You need substantially more multicore performance - You need newer connectivity that your current board cannot offer ### Upgrade makes less sense if - The GPU is the real bottleneck - Current applications are already responsive - The CPU rarely limits your workload ## Specifications Figures below follow the Feex Hardware Database record for this SKU.

Check the motherboard CPU list and BIOS revision. | | Memory | DDR5, up to 1.5 GB | | Graphics | Requires a discrete GPU. This SKU has no iGPU. | A shared socket is not automatic compatibility. Boards often need a BIOS update before a newer chip in the same socket will post. Cooler clearance, VRM quality, and power limits matter as much as the socket name. Do not expect a display from the motherboard video ports. This SKU has no integrated graphics. ### No display after install This SKU has no integrated graphics. A machine with no discrete GPU will not show a picture. That is expected, not a dead CPU. ## Related These entities connect to this article. Type is shown on every link.
