Cores: Up to 24
Base price: $600 to $3,600
With a reasonable price-to-performance ratio, Silver excels at a wide variety of enterprise applications. Strong single-threaded speed thanks to high base clocks makes Silver fantastic for latency-sensitive tasks as well.
Maximum Horsepower: Xeon Gold
Xeon Gold Series
Target workloads: High-performance computing, simulations, big data analytics, AI inferencing, virtualized clouds
Cores: Up to 28
Base price: $1,500 to $8,000
If you need raw multi-threaded CPU grunt, look no further than Xeon Gold. With high core counts, massive amounts of cache, quad-channel memory support and oodles of PCIe bandwidth, Gold is purpose-built for today’s most demanding server workloads.
The Top of the Xeon Food Chain: Xeon Platinum
Xeon Platinum Series
Target workloads: Machine learning training and inferencing, modeling, simulations
Cores: Up to 56
Base price: $3,000 to $50,000 (!)
As the pinnacle of Xeon performance, Platinum pulls out all the stops. With up to 56 high-clocked cores, 12 memory channels, and specialized deep learning acceleration, Platinum crushes even the most intense computing challenges with ease. Just be prepared to shell out for the privilege…
Xeon Scalability, Memory, and Platform Support
A key advantage of Xeon over consumer chips is seamless scale-out capacity. Most models utilize one of twoserver-grade sockets for connecting to system boards:
- Socket P (LGA 3647): Used for Platinum, Gold, and some Silver models. Supports up to 8 sockets for 4/8-way multiprocessing
- Socket B (LGA 4189): Used for Bronze, some Silver models, and special use-case Xeons. Supports up to 2 sockets.
This enables companies to start out with an affordable dual-socket server, then seamlessly scale out to 4, 6, or even 8 sockets by swapping Xeon CPUs down the road.
In addition to more cores, server-class Xeons boast vastly higher memory capacity:
- Up to 1.5TB of blisteringly-fast DDR4 ECC RAM per socket
- Up to 12 channels / 6 DIMMs per channel
- Support for Optane Persistent Memory 200 Series
This allows Xeon systems to keep enormous datasets in memory for rapid access during processing.
Comparing Intel Xeon vs AMD EPYC
Intel enjoys a dominant 80% market share in data centers. But AMD is catching up with its powerful EPYC server CPU family, offering compelling advantages:
More Cores & PCIe: Current top-end AMD EPYCs like the 7763 offer 64 high-performance Zen 3 cores, 128 threads, and a whopping 128 PCIe Gen 4 lanes. Intel can’t match this density.
Memory Bandwidth: Thanks to its chiplet architecture, EPYC supports a staggering 12 channels and 3200+ MHz speeds even on mid-tier models. Xeon offers higher capacity however.
Cost Per Core: $/core, AMD offers better value from entry-level to top-end SKUs. Though Intel often wins in absolute per-clock performance.
Performance Leadership: Xeon still wins many absolute performance benchmarks thanks to Intel’s advantages in memory latency, optimizations, and clock speeds.
For most data center needs, both vendors offer excellent options. AMD shines when density of cores, memory bandwidth, and cost efficiency are priorities, while Intel excels at raw clock speed.
When Xeon Makes Sense (And When It Doesn’t)
With so many different models targeting varied applications, who should actually buy Xeon?
Ideal Xeon Use Cases
- Web servers
- Databases and data warehousing
- High performance computing
- Financial and scientific modeling
- Engineering simulations and CAD
- Media encoding/transcoding

In summary, if you need a combination of strong multi-core performance, excellent memory support, corporate-grade security and reliability features, and cutting-edge hardware accelerators, Xeon is a fantastic choice.
Finding the Right Intel Xeon CPU For You
With so many options on the table, selecting the ideal Intel Xeon model for your infrastructure can be tricky. Here is a handy decision tree:
[INSERT INFOGRAPHIC]-
What’s your budget? Under $1,000? Choose Bronze or E-Series. Over $2,000 per processor? Look at Gold or Platinum.
-
What server form factor? 1U/2U fits D and E Series well. 4U+ works with any.
-
Do you need built-in networking? Xeon D includes this.
-
How many PCIe lanes? At least 64? Go with Platinum or AMD. 32? Gold or EPYC work.
-
What memory capacity per socket? Up to 1.5TB? Platinum. 768GB? Gold. 128-256GB? Silver or Bronze.
Using this decision process, you can quickly narrow down to a shortlist of suitable Intel Xeon processors for your workload based on critical factors like budget, platform support, and resource requirements.
The Bottom Line
While the dizzying array of Xeon models provides no shortage of choice on paper, comparing specs only goes so far. Nothing beats hands-on testing with your target applications to see which processor family offers the right fit.
Most data center operators standardize on one or two preferred Xeon families across generations to simplify infrastructure management. If unsure, it rarely hurts to start in the middle with flexible all-rounders like Xeon Silver and Gold CPUs.
Thanks to strong vendor partnerships and continual innovation, Intel Xeon has earned its place as the world’s most ubiquitous data center platform. We can’t wait to see what the next 25 years of Xeon innovation brings!
