Game Consoles Are Computers Too 🎮💻
One of the biggest misconceptions I see with beginners is the idea that a gaming console and a computer are two completely different things. When people hear the word "computer" they think of a desktop or a laptop, and when they see a PlayStation or an Xbox they think of it as something else entirely. But here is the truth: every game console is a computer. It has a CPU, a GPU, RAM, and storage, just like the gaming PC sitting on your desk.
In this post I am going to break down the hardware inside three popular consoles, the Nintendo Switch 2, PlayStation 5, and Xbox Series X, and compare them side by side with a gaming PC. My goal is to help you see that the same fundamentals we have been covering in this series apply to every gaming system, not just PCs.
The Hardware Inside Your Console
Let us start by looking at what is actually inside these consoles. If you have been following the other posts in this series about RAM, CPUs, GPUs, storage, and motherboards, all of these terms should look familiar.
CPU
8-core ARM Cortex-A78C @ ~1.1 GHz
8-core AMD Zen 2 @ 3.5 GHz
8-core AMD Zen 2 @ 3.8 GHz
GPU
1536 CUDA cores (Ampere)
36 CUs RDNA 2 @ 2.23 GHz (10.28 TFLOPS)
52 CUs RDNA 2 @ 1.825 GHz (12 TFLOPS)
RAM
12 GB LPDDR5X (9 GB for games)
16 GB GDDR6
16 GB GDDR6
Storage
256 GB internal
825 GB custom NVMe SSD
1 TB custom NVMe SSD
Ray Tracing
Yes (via Ampere)
Yes (hardware accelerated)
Yes (hardware accelerated)
Target Resolution
1080p handheld / 4K docked
Up to 4K @ 120 FPS
Up to 4K @ 120 FPS
Look at that chart. CPUs with multiple cores and clock speeds. GPUs with dedicated compute units. Gigabytes of RAM. NVMe solid state storage. These are computers. The same components we have been talking about throughout this entire series are sitting inside every one of these consoles.
Breaking Down Each Console
Nintendo Switch 2
The Switch 2 is the most unique of the three because it is a hybrid handheld and home console. It runs on an NVIDIA Tegra T239 chip, which packs an 8-core ARM CPU and an Ampere-based GPU with 1536 CUDA cores onto a single chip. This is very similar to how a laptop combines its components into a compact, power-efficient package.
With 12 GB of LPDDR5X RAM (9 GB available to games) and support for DLSS 3.1, the Switch 2 can use the same AI upscaling technology found in NVIDIA's desktop RTX GPUs. That is desktop-class technology running in a device you can hold in your hands. It has 256 GB of internal storage, which is modest by today's standards but makes sense for a portable device.
PlayStation 5
The PS5 runs on a custom AMD APU (Accelerated Processing Unit) that combines a Zen 2 CPU and RDNA 2 GPU on a single chip. This is the same fundamental architecture found in AMD's Ryzen desktop CPUs and Radeon desktop GPUs, just customized for Sony's needs.
Its 16 GB of GDDR6 RAM serves as unified memory, meaning both the CPU and GPU share the same pool, similar to how integrated graphics work on a PC. The PS5's custom SSD is particularly impressive, delivering 5.5 GB/s raw bandwidth with a dedicated decompression unit that can push effective throughput even higher. This custom storage architecture is one reason PS5 games can load so quickly.
Xbox Series X
The Xbox Series X also uses a custom AMD APU with Zen 2 CPU cores and an RDNA 2 GPU. Its GPU is actually the most powerful of the three consoles at 12 TFLOPS, with 52 compute units compared to the PS5's 36. It has 16 GB of GDDR6 RAM split into two tiers: 10 GB of faster memory at 560 GB/s for the GPU-intensive work and 6 GB of slightly slower memory at 336 GB/s.
The 1 TB custom NVMe SSD provides fast storage out of the box, and Microsoft's Velocity Architecture is their answer to optimizing how game data flows from the SSD to RAM, similar in concept to what the PS5's custom I/O does.
How Do They Compare to a Gaming PC?
Here is where it gets interesting. Let us put a typical mid-range gaming PC alongside these consoles:
CPU
AMD Ryzen 5 7600 (6-core Zen 4 @ 5.1 GHz)
8-core Zen 2 @ 3.5-3.8 GHz
GPU
NVIDIA RTX 4060 Ti (4352 CUDA cores, 8 GB VRAM)
Custom RDNA 2 (10-12 TFLOPS, shared memory)
RAM
32 GB DDR5
16 GB GDDR6 (shared with GPU)
Storage
1-2 TB NVMe Gen 4 SSD
825 GB - 1 TB custom NVMe SSD
Upgradeable
Yes, every component
Limited (storage expansion only)
Price
~$900-1200
~$499
The consoles hold up remarkably well considering they launched at $499. The reason they can deliver strong gaming performance at a lower price point is optimization. Console developers know exactly what hardware every player has, so they can fine-tune their games to squeeze every bit of performance out of that specific configuration. PC games have to account for thousands of different hardware combinations.
However, the PC has clear advantages in flexibility, upgradeability, and raw horsepower. You can swap out your GPU when a new generation launches, add more RAM, install faster storage, and adjust every graphics setting to your preference. A console is a sealed package that you live with until the next generation.
The Same Fundamentals Apply
This is the key takeaway. Whether you are playing on a Switch 2, a PS5, an Xbox, or a gaming PC, the same hardware principles are at work:
The CPU is processing game logic, AI, physics, and input, the same fetch-decode-execute cycle we covered in the CPU post
The GPU is rendering every frame through the graphics pipeline, rasterizing, shading, and outputting pixels to your display
RAM is holding the actively used game data so the CPU and GPU can access it quickly, and when it runs out, performance suffers
Storage is feeding game assets to RAM as fast as it can, and faster storage means smoother streaming and shorter load times
Even the motherboard concept applies. Inside every console is a main board connecting all these components together
When a PS5 game stutters, it is because the CPU or GPU could not finish the frame in time. When an Xbox game has texture pop-in, it is because the storage could not feed data to RAM fast enough. When a Switch 2 game runs at a lower resolution in handheld mode, it is because the GPU is running at reduced clocks to save battery and manage heat. These are the exact same principles that apply to PC gaming.
Why This Matters
Understanding that consoles are computers demystifies technology. If you can understand why a PS5 loads games fast (custom NVMe SSD with a dedicated decompression unit), you already understand why NVMe drives matter in a PC. If you know that the Xbox Series X has 16 GB of RAM shared between the CPU and GPU, you understand the concept of unified memory and why dedicated VRAM on a PC GPU is an advantage.
This knowledge transfers across platforms and even into other fields. The same CPU, GPU, RAM, and storage concepts show up in:
Smartphones — Your phone has a CPU, GPU, RAM, and flash storage, just like a console
Cloud computing — Servers in data centers use the same components at scale
Cybersecurity — Understanding hardware helps you understand how exploits and vulnerabilities work at a deeper level
IT careers — Troubleshooting a slow workstation uses the same diagnostic thinking as figuring out why a game is stuttering
The Bottom Line
Next time you pick up a controller, take a moment to appreciate the fact that you are holding a computer interface connected to a machine that has a multi-core CPU, a dedicated GPU, gigabytes of high-speed RAM, and solid state storage, all working together to render a virtual world in real time.
Consoles and PCs are not different categories of technology. They are different form factors of the same technology, built on the same fundamentals, solving the same problems, just packaged differently. Once you see it that way, the world of computing opens up in a whole new way.
Keep playing and keep learning!
