A simple look at the requirements details would reveal that the minimum processor you should aim for is the one with 2.5-2.9 GHz clock speed on a single.

However, the recommended specification is to go for a 3+ GHz clock speed processor. The key point to note here is the “+” sign. This basically entails the faster higher the better.

It should also be quite clear here that AutoCAD would benefit the most from a single high performance thread rather than having multiple cores and thus having multiple threads.

We explore the idea of threads and cores below. But for now, the key idea to take away is that you need to find a processor with the highest Clockspeed per core.

The processors we have selected here at least meet the recommended specifications.

1. AMD Ryzen 5 3600XT – Recommended Processor for AutoCAD

AMD Ryzen 5 3600XT

High-Mid range Ryzen 5 processor from the third generation.

First up, we have our personal favorite. If you want to go straight toward one of the most popular processors of the current generation, then this is highly recommended.

The value proposition of this processor is that it features both a good performance as well as offers a fairly reasonable price tag.

Therefore whether you are a beginner or an intermediate user, this is one of the best processors for AutoCAD.

The key feature of this CPU is that it features a single Core performance of 4.5 GHz. This is far more than the recommended 3 GHz for AutoCAD.

As far as the core counts go, this features 6 cores with AMD hypertransport. As such, it has 12 processing threads.

While multiple threads and cores will give you minimal benefit on AutoCAD, other application, games and even just background apps will see great benefit from the higher core count.

This processor works on the AMD AM4 socket and the most recommended motherboard chipset to go for is the AMD B550 for mid range builds and AMD X570 for high end builds.

What Kind of Processor to Buy For AutoCAD?

As mentioned earlier above, the first and foremost important thing to consider is the recommended requirement of the software itself.

The recommended requirements state that the single thread performance of a processor should be 3+ GHz. Hence the best CPU for AutoCAD you should aim for is the one that has a high single core clock speed.

Do Core Counts Matter for AutoCAD?

Autocad is generally regarded as a single threaded software.

A core basically translates to a single or dual threads. Dual threads per core is only possible if the processor has hyperthreading (Intel) or hypertransport (AMD) enabled.

A quad core processor, for instance, can have a four threads at a minimum or 8 threads if it has multithreading technologies mentioned above enabled.

The higher the number of Cores, the more simultaneous tasks it can perform. The higher the number of threads, the higher still is the number of tasks your PC can perform at once.

However, not all software are designed to utilize all cores and thread.

Since AutoCAD is regarded as a single threaded software in most cases, you will benefit more from a single core having a very high clock speed then having a processor with multiple cores but with slower clock speed.

Fortunately, most of the desktop grade processors from the Intel Core i3 to Core i9 and AMD Ryzen 3 to Ryzen 9 have a single threaded clockspeed of 3+ GHz.

The Higher the Clockspeed the Better for AutoCAD

While the recommended requirement is to meet the 3 GHz mark, the higher the better.

For instance the Intel Core i9-10850K with a clock speed of 5.2 GHz would be far better performing than the AMD Ryzen 3 3100 with 3.9 GHz. However, whether the cost benefit is worth it depends on you.

Is an Intel Core i3 or an AMD Ryzen 3 Enough for AutoCAD?

Yes. The simplest answer to your question is that both of these processors (from the latest generations) meet the recommended requirements of the software.

Hence, they can mostly operate the software. However, whether you will be happy with the performance or not is another question.

AutoCAD is highly reliant on CPU for performance. While an Intel Core i3 or an AMD Ryzen 3 will operate the software fine, for more complex and large projects, you will want to upgrade your processor.

Final Words

Here we looked at some of the best processors for AutoCAD from different price brackets, generation as well as from both Intel and AMD.

Before purchasing the right processor, you should be mindful your budget and your requirements. It is recommended that you maximize your budget for two components i.e processor primarily and then the RAM.

RAM should be at least 8 GB but the recommended amount is 16 GB.

We hope this article at least points you to the right direction.
