IntelServer CPUCascade Lake

Intel Xeon Gold server processor on Cascade Lake, with 18 cores and 36 threads and 24.75 MB L3 at 150 W TDP on a 14 nm process addressing up to 1 GB and no integrated graphics.

What you need to know

Intel Xeon Gold 6240 is a legacy server cpu.

Intel Xeon Gold 6240 launched in April 1, 2019., It has 18 cores and 36 threads on Cascade Lake, dropping into the FCLGA3647 socket. Treat the spec table as the facts. Age alone does not tell you to throw it out.

Still good?: Yes, for lighter work
Product age: 7 years old
Upgrade pressure: Moderate

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: Good. Good for the class when RAM, storage, and the GPU keep up.
Product age 7 years old: Legacy. Launched April 1, 2019. 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: Moderate. Upgrade pressure comes from platform features and specific CPU-bound work, not from the chip being unusable.

Where does it sit?

Cascade Lake sits on Intel's recent Core timeline. Later desktop branding moved toward 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: Good

18 cores cover office, browser, and compile work in this class.

Multithreaded workloads: Very Good

36 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 150 W base power. That is a platform number, not a promise about your cooler.

Should you upgrade?

Probably not based on CPU performance alone.

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

Compatibility

Compatibility
Socket	FCLGA3647
Board	A shared socket is not automatic compatibility. Check the motherboard CPU list and BIOS revision.
Memory	DDR4, up to 1 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.
