The Intel budget category of CPUs can get a bit confusing. You have Intel Celeron, Intel Pentium, and Intel Core i3, all in the seemingly “budget” or “entry-level” categories of CPUs.
Having so many lines of budget CPUs seems a bit redundant. However, there are a lot of differences between Pentium and Core i3 processors that make them quite distinct from each other.
The main difference between the Pentium and Core i3 Processors is that the Intel Pentium CPUs are INFERIOR to the Intel Core i3 CPUs in terms of PERFORMANCE. However, they are also cheaper.
The clear distinction of price and performance between these two Intel CPUs lines makes them quite viable for their respective market segment.
Let’s explore the differences between the two in more detail. After all, my goal is to help you make the best decision.

General Overview
Pentium Processors
Pentium processors were first introduced by Intel in 1993 and have since gone through several iterations. The Pentium range of processors is designed for low-end to mid-end use cases and typically in budget-friendly computers and laptops.
These processors have a single core and are based on a 32-bit architecture. This means they can handle only up to 4GB of memory, which is less than the 64-bit architecture of Core i3 processors that can take more than 4GB of memory. Pentium processors also have lower clock speeds than Core i3 processors, typically ranging from 1.8GHz to 3.2GHz. Regarding TDP (Thermal Design Power). Pentium processors consume less power than Core i3 processors, which are usually 35W or higher.
In terms of performance, Pentium processors are generally less potent than Core i3 processors. They are best suited for basic tasks like web browsing, document editing, and media playback. However, they are not well suited for more demanding gaming and video editing tasks.
Core i3 Processors
Core i3 processors were introduced by Intel in 2010 and are part of the Intel Core series of processors. They are typically found in mid-range computers and laptops and offer a balance of performance and cost.
These processors have two cores and are based on a 64-bit architecture. This means they can handle more than 4GB of memory and are better suited for more demanding gaming and video editing tasks. The Core i3 processors also have higher clock speeds than Pentium processors, typically 2.4GHz to 4.0GHz. Regarding TDP (Thermal Design Power), Core i3 processors consume more power than Pentium processors, usually 35W or higher.
In terms of performance, the Core i3 processors are generally more potent than Pentium processors and better suited for multitasking and running multiple applications simultaneously. They are also better suited for more demanding gaming and video editing tasks.
Important Note: When Comparing, Select CPUs from the Same Generation!
Before comparing any two CPUs or a CPU line, it is essential that you compare them ideally from the same generation.
For instance, you cannot compare a 10th Generation Intel Core series processor with a decade-old Pentium processor.
Also, always use the benchmarks such as Passmark or the Cinebench R15 and Cinebench R20 to figure out the performance difference instead of relying on sheer specs.
With that in mind, let us discuss the differences between Intel Pentium and Core i3 CPUs with examples.

Let’s Compare a Pentium and a Core i3 CPU of the same generation
Basically, given any CPU generation, the Intel Core i3 has a superior performance to Intel Pentium.
For Instance, considering the recent “Comet-Lake” or 10th Generation DESKTOP-BASED Intel CPUs, the Intel Core i3 offers four cores, whereas the Intel Pentium CPUs offer 2 cores.
The table below explains the key features considering current 10th Gen (Comet-Lake) CPUs.
Intel Pentium | Intel Core i3 | |
Current Flagship CPU (Desktop) | Intel Pentium Gold G6600 (Q1 2021) | Intel Core i3 10320 (Q2 2020) |
Core Count | 2 | 4 |
Hyper-Threading | Yes (4 Threads) | Yes (8 Threads) |
Clock Speed | Lower Clock Speed | Higher Clock Speed |
Boost Clock Speed | None | Yes |
Cache | Lower Cache | Higher Cache |
Cost | Cheap | Higher |
Purpose | Light day-to-day work such as browsing, school work, writing reports, light casual gaming etc. | Entry into the Performance Grade PC Builds, For AAA gaming at a budget, for working on professional software with light workloads |
Basically, both Intel Pentium and the Intel Core i3 serve two very different purposes.
Intel Pentium is intended for those who have a fundamental computing demand. So, if you are looking for a CPU for day-to-day computing, such as writing emails, watching movies, researching, and surfing the web, Pentium is the way to go.
Once you start delving into the Intel Core i3 series, you are now beginning to scratch the surface of performance-grade CPUs. These are intended for gamers and professionals on a budget.

Performance and Cost Benchmarks
One of the most significant advantages Intel Pentium has to its side is its cost. An Intel Pentium CPU typically costs almost HALF as much as an Intel Core i3 CPU.
The question is: Are Intel Pentium CPUs HALF as much powerful as Intel Core i3 CPUs?
The following table should explain this further:
Specs | MSRP ($) | Cinebench R15 (Single Core) | Cinebench R15 (Multi Core) | Passmark | |
Intel Core i3 10320 (Flagship) | 4/8 (c/t) 3.8-4.8 GHz | 162 ($) | 206 | 1080 | 10127 |
Intel Core i3 10100 (Value) | 4/8 (c/t) 3.6-4.3 GHz | 122 ($) | 191 | 1001 | 8825 |
Intel Pentium G6600 (Flagship) | 2/4 (c/t) 4.2 GHz | 93 ($) | 176 | 437 | 4396 |
Intel Pentium G6400 (Value) | 2/4 (c/t) 4.0 GHz | 64 ($) | 166 | 416 | 4155 |

- Passmark scores taken from cpubenchmark.net
In the table above, we have selected two DESKTOP-BASED CPUs from both Intel Core i3 and Intel Pentium (latest Gen).
The flagship CPUs are expensive with a lower performance/dollar value, whereas, the popular “value” based CPUs have a better performance/dollar value.
I would always use the “value” based models if I were you. Anyhow, I digress. Going back to the benchmarks above, we can see some exciting results.
Not a Huge Single Core Performance Difference Between the Two
When comparing the single-core performance, there isn’t a significant difference between Intel Pentium and Intel Core i3 processors.
There is perhaps a 14-15% difference between the two in single-core performance.
The single-core performance is an essential factor of a CPU as it determines how well it would perform on single-threaded applications.
Most popular online games, for instance, Fortnite, Minecraft, etc. Still rely more on the single-core prowess of a CPU than its multi-core performance.
However, single-core performance is only one part of the equation for a CPU.

Significant Multi-Core Performance Difference Between the Intel Pentium and Core i3
The critical difference between the two series is in their multi-core performance difference. Regarding multi-core performance, the Intel Core 3s are about 60% more powerful than the Intel Pentium CPUs.
As mentioned earlier, Intel Core i3 CPUs have twice as many cores as Intel Pentium CPUs (given the current gen), and hence naturally, they have at least twice as good a multi-core performance.
The multi-core performance of a CPU determines how well it can multitask and how well it can handle apps and services running simultaneously.
PCs, apps, and games today are complex. You can have so many critical background applications and services running in the background without you even knowing about them.
Having more cores can significantly improve your experience, mainly if you are a gamer or someone who works on professional software.

For Gaming, Aim for at least a Quad Core CPU
There was a time half or so decade ago when games did not scale well with multiple cores. A decade ago, an Intel Pentium would have given you almost the same performance as an Intel Core i3 CPU in gaming.
Take League of Legends, released back in 2009, for example. This old title is still playable on high graphics on even an entry-level Intel Celeron G390 released back in 2017.
However, modern AAA games and their engines are designed to scale well with multiple cores. Hence, if you are even remotely a AAA title gamer, a Quad-Core Intel Core i3 CPU is the least I would recommend today.

Balancing Single and Multi-Core Performance
An over-the-top multi-core score doesn’t always mean better performance.
For instance, the Intel Core i9-11900K, the workstation-grade CPU with 8 cores and 16 threads, scores a whopping 2575 on Cinebench R15. Compare this to a mere 1080 for Intel Core i3-10320.
However, if your workload does not use many cores and threads, you will not see any performance difference in your games or applications.
Professionals often use an over-the-top core count. It is used in video rendering, simulation, machine learning, and also for simulation games such as Cities: Skyline and Microsoft Flight Simulator.

Differences In Laptop-Based Intel Core i3 and Pentium CPUs
Regarding mobile or laptop-based CPUs, the critical overall performance difference mirrors that of the desktop-based variant, i.e., the Intel Core i3 is twice as powerful, whereas the Pentium is half as cheap.
However, there are a few key spec differences. For one, the laptop-based Intel Core i3 has the same amount of cores as the Intel Pentium.
The real winner for Intel Core i3 for laptop-grade CPUs is the Turbo boost frequency. The Intel Core i3-10110U can reach speeds of a whopping 4.1 GHz per core – almost twice as high as that of the Intel Pentium Gold 6405U.
Specs | MSRP ($) | PassMark (Single Core) | PassMark (Multi Core) | Passmark (Overall) | |
Intel Pentium Gold 6405U (Flagship) | 2/4 (c/t) 2.4 GHz | 161 ($) | 1413 | 2313 | 2359 |
Intel Core i3-10110U (Flagship) | 2/4 (c/t) 2.1-4.1 GHz | 281($) | 2313 | 4006 | 4064 |
