Workstation workloads require powerful processors but which one to choose
from the blue team?

FULL STORY ======================================================================

Since the launch of the Xeon brand in the late 1990s, Intel has touted that family of processors as the optimal choice for most professional
applications, be it in mobile workstations , in traditional workstation PCs
or video editing PCs .

But over the years, the advantages of Xeon have been eroded as Intels consumer-oriented Core brand added features and increased in both core count and core frequency, narrowing the gap. So, given the current gen Intel Xeon and Core options, which should professionals use? Here's our list of the best business computers right now These are the best video editing laptops on the market We've built a list of the best business laptops out there Core pros

Overclocking Unlocked i5, i7, and i9 processors are designed to be overclocked, meaning they can run at higher clock speeds than what theyre qualified for, assuming the right voltage and BIOS settings (and cooling and paste). This equates to free power and more value, a feature that Xeons do
not have and can thus translate to faster professional renders in many cases, especially where frequency is a key spec.

GHz per dollar For pure Gigahertz speed for the money, the LGA2011 (X299) and 1200 (Z590) Core models come out on top every time, making them the best value for single threaded and lightly threaded applications. For example, an 8-core i7-11700k which runs at 3.6/5.0GHz retails for around $400. The comparable Xeon running at that clock speed will cost about $100 more. For
pro users with single threaded or lightly threaded software, this increases value tremendously.

Onboard graphics Aside from the F SKUs, Core processors all come with onboard graphics, meaning a discrete video card is not required for video display, whereas Xeon processor-based PCs cannot be configured without discrete video. Though I recommend a discrete card for anything beyond mostly casual work, onboard graphics are suitable for many home office users or professionals primarily focused on CPU rendering. Xeon pros

L3 cache CPU caches are like small batches of memory that the processor keeps close by to speed up certain applications. Most Xeon processors have 15-30MB and as much as 50MB+ of L3 cache depending on the model, close to double their i7 counterparts. This extra cache is one reason why Xeons are often so much faster at high demand professional applications than Core.

Support for ECC RAM Error Checking and Correction (ECC) RAM detects and corrects most common data corruption before it occurs, eliminating the cause of many system crashes and translating to more stable overall performance. Only Xeon processors fully support ECC RAM. To me, this is the single most important feature that Xeon offers over Core since ECC is especially
important with higher RAM densities and with higher demand use cases where
RAM failures are both more common and more devastating when they do occur.
How this changes in the future with the release of DDR5s standard on die ECC remains to be seen, but early reports are that Xeon will still be required
for full ECC DDR5 support.

RAM Density For professionals working in applications that require very large quantities of Memory, Xeon may be not only the best, but the only option. Intel Core currently maxes out at 256GB of 8-channel DDR4 but
Scalable Xeon and the new Xeon W-3300 support up to 4TB (that is, assuming
you can find 256GB modules to fill all 16 DIMMs) making them ideal as web hosting servers

More cores, multi-CPU options For heavily threaded applications that will benefit from as many CPU cores as possible (think Machine Learning or Computational Fluid Dynamics among others), Xeon is what you need. For example, the latest Xeon Scalable processors max out at 40 cores/80 threads and as the name suggests, can be scaled to multiple sockets. In contrast,
even the i9-10980XE , the most heavily threaded Core processor currently, has just 18 cores.

Architecture Designed for Efficiency Xeon processors generally use
different CPU architectures and process nodes which support both these cache and core count improvements, but also offer more efficient power with a lower TDP. This translates to less heat generated, more heat dissipated, and less stress on the hardware long term, making them ideal for high stress workloads on a day in, day out basis. For the serious workstation user, this can translate to better longevity over Intels Core counterparts. Which is best
for professionals?

So, which is best for you? That answer depends on what specific professional applications youll be using your new PC for and the price point at which you feel most comfortable. If your workflow consists of 4K video, 3D rendering , or VFX in applications like AVID, Premiere Pro , Blender, Ansys, or Houdini where the benefits of ECC RAM, more cache, and possible dual CPUs with a multitude of cores are advantageous, I heartily recommend Xeon.Its really the only choice at that tier, and will reap rewards in the way of reduced render times and overall productivity. But, if your usage is more mainstream to moderate or you primarily use more single threaded applications like Revit or AutoCAD, Intel Core offers much better value and may even perform better in those specific cases. The key is to know what you do, what you need, and to not let yourself be oversold on hardware that wont make you more productive. What about the Pentium?

Those who might be tempted to buy a Pentium processor because of perceived savings should reconsider their decisions. The most powerful Pentium CPU released to date, the G6605, is still far, far slower than any 10th
generation Intel Core i3 processors which, by default, come with four cores and eight threads (as opposed to four threads and two cores for the Pentium model).

Its really the only choice at that tier, and will reap rewards in the way of reduced render times and overall productivity. But, if your usage is more mainstream to moderate or you primarily use more single threaded applications like Revit or AutoCAD, Intel Core offers much better value and may even perform better in those specific cases. The key is to know what you do, what you need, and to not let yourself be oversold on hardware that wont make you more productive. Here's our list of the best Windows 10 Pro laptops
