The Pros of Intel Core i9/i7/i5 CPUs

• Clock Speed and Overclocking 
• Onboard Graphics 
• CPU Cost and GHz per Dollar 

Clock Speed and Overclocking  

Core CPUs have higher clock speeds and overclocking capacity compared to Xeon processors. Intel Core CPUs can achieve high clock speed with overclocking, right voltage, correct BIOS settings, and adequate cooling solutions. Whereases Xeon processors cannot perform overclocking. Faster clock speed translates to faster CPU calculations, which means smoother application performance for software relying on the CPU’s clock speeds. Overclocking feature is available for Core i5, Core i7, and Core i9 processors.   
 

Onboard Graphics  

Another advantage of Intel Core CPUs over Xeon processors is they come with onboard graphics. Integrated graphics eliminate the need for an additional dedicated graphic card for video and image processing. In contrast, computers with Xeon processors need a discrete video card for video display. However, the onboard graphics are only fit for regular office use. Dedicated graphics cards are still required for Intel Core and Xeon CPUs for heavier graphics workloads.  
 

CPU Cost and GHz per Dollar  

When comparing the cost between Core and Xeon CPUs, the difference can range from hundreds to thousands of dollars. Intel Xeon processors are much more expensive because they often include more cores, feature advanced technologies, and are highly reliable for mission-critical applications. That is why Intel Xeon processors are aimed mainly at enterprises and industrial applications that find it worth investing in high-end CPUs. Here is a quick price comparison for Intel Core vs Intel Xeon lineups.  

The Price Ranges of Intel Core CPUs: 
Core i3 costs around $100 to $200  
Core i5 costs around $200 to$300  
Core i7 costs around $300 to $400  
Core i9 and Core X-series cost around $500 to $600  

The Price Ranges of Intel Xeon Server CPUs are much more extensive. The cheapest Intel Xeon CPUs start at around $230, and one of the most expensive Intel Xeon Platinum 8180 costs a whopping $15000, such a huge gap compared to the Intel Core lineup.  
 

When should you consider getting Intel Core CPUs?  

For low to medium-tier applications that are not mission-critical, the Core CPUs are a much better choice that offers better single-core performance and cost less than most Xeon processors. Intel Core i3 and i5 CPUs are great for web browsing, streaming music and video, faster startup speed, and even 4K graphics support; the Core i7 and i9 CPUs are good for more intensive software that relies on single-core computations, and they even outpace some Xeon CPUs for single-threaded applications such as Revit and AutoCAD.  

 

The Pros of Intel Xeon Server CPUs  

• Number of Cores and Hyperthreading 
• L3 Cache Memory 
• ECC RAM Support 
• RAM Capacity and Bandwidth 
• Efficiency and Longevity 

Number of Cores and Hyperthreading  

More CPU cores will result in more multitasking capabilities and increase processing power for parallel computing. The numerous cores on a single Intel Xeon processor can support heavily threaded applications from machine learning to computational fluid dynamics. The latest Intel Xeon Scalable processors have up to 40 cores and 80 threads compared to Intel Core CPUs. Moreover, Xeon processors support multiple CPU configurations for even more cores, memory bandwidth, and I/O slots. In contrast, the latest Intel 10th Generation Comet Lake CPUs with the Core i9 models can have a maximum of 10 cores and 20 threads on a single processor.  
 

L3 Cache Memory  

CPU cache memories are divided into three grades, level 1 (L1), level 2 (L2), and level 3 (L3). The difference between L1, L2, and L3 is that L1 is the cache memory that is the closest and fastest to the CPU since it is usually built onto the microprocessor chip itself. L2 is slower than L1 but faster than L3 cache. Then the L3 memory, or the external cache, is the slowest cache but still twice as fast as RAM (random access memory). All the CPU cores share the same L3 cache memory, where more L3 cache memory leads to faster processing as the CPU can access more data faster from the L3 cache. Most Xeon processors have 15-30MB of L3 Cache, and some with more than 50MB, which is double the cache memory of Core i7 CPUs.  
 

ECC RAM Support  

Error Checking and Correction RAM or ECC RAM support is one of the most critical advantages Intel Xeon CPUs have over Intel Core CPUs. ECC RAM eliminates the high risk of corrupted memory data, one of the most common causes of software crashes. A software crash is the last thing you want to happen to mission-critical applications. Therefore, ECC RAM ensures the performance stability of rugged servers and high-end workstations. ECC RAM also supports much more significant amounts of RAM than DDR4 RAM, which results in smoother application performance.   
 

RAM Capacity and Bandwidth  

Another great advantage of Xeon processors over Core CPUs is the ability to support higher RAM density. As a result, the lowest Xeon models can easily outperform the latest Intel Core i7 and i9 CPUs for RAM capacity and memory channel support. For instance, the 10th Generation Intel CML Core i9 CPU supports up to 128 GB of RAM and two memory channels. In contrast, one of the cheapest Xeon models, the Xeon Bronze 3104 processor, supports up to 768 GB of RAM and six memory channels, adding much more RAM capacity and bandwidth.  
 

Efficiency and Longevity  

Intel Xeon processors are highly-efficient CPUs that are built to handle continuous heavy and intensive loads 24/7 without fail. For mission-critical servers and workstation users, Xeon CPUs can provide better value for longevity than the Intel Core CPUs. This is why Intel Xeon CPUs do not support overclocking. Xeon processors have a higher TDP than Core CPUs, which means if they try to bump up the clock speeds, there is a risk of thermal throttling or even failure. That is why Xeon CPUs are more stable and energy-efficient, crucial for rugged servers and workstations.  
 

When should you consider getting Intel Xeon Server Processors?  

Despite the high price, Xeon processors can be worth it for mission-critical applications where enterprises can save hundreds of thousands and even millions by eliminating downtime risks. Not only are Xeon processors more reliable and durable, but they also support rich features that take the overall performance and scalability to the next level. Furthermore, the Xeon processors can support data-intensive applications such as machine learning and even offer virtualization support. Xeon processors provide complete chain virtualization support that allows server workloads to be virtualized.  

 

Server Class Performance with Embedded Design

Intel initially developed Intel Xeon processors for server computers in data centers with many cores and numerous PCIe lanes. However, greater demands for edge computing applications are migrating computing from the cloud to remote and mobile environments. Processing localized workloads closer to the IoT sensors and devices allow intelligent edge solutions to perform real-time processing for mission-critical applications. One of the highest demands for AI edge applications is real-time inference and computer vision for machine intelligence. Machine learning and intelligence provide automation for various edge solutions, including robotics, vision, motion control and even self-driving cars. A key challenge for new edge computing models is deploying reliable frameworks of computing architecture near where data is generated. In terms of rugged edge computing, a variety of these new workloads are shifting in harsh environments that require durable rugged computers that have been designed with a balance of performance and power optimization in mind. Today, even leading semiconductor designers are packaging incredible amounts of performance with specific processors designated for low-power budgets but incredible processing performance.  
 

Now, rugged AI edge inference computers can even utilize Intel Xeon CPUs with 35W of thermal design power (TDP) to unlock Xeon's powerful features for server-grade performance at the rugged edge. Configuring Intel Xeon CPU with 35W of TDP allows the computer to be fanless, which offers industrial-grade durability for rugged edge computing.
