What is CUH in PS4? A Comprehensive Guide to PlayStation 4 Model Codes and Differences

As an avid gamer and tech enthusiast, I‘ve owned and played every version of the PlayStation 4. One thing I noticed early on is that Sony assigns all PS4 models a code starting with "CUH." If you‘ve ever wondered what CUH means or how to decode the PS4‘s model numbers, then this guide is for you!

I‘ll provide an in-depth look at the CUH model codes and explain all the differences between PS4 models so you can better understand what you have or plan to buy. Let‘s dive in!

A Brief History of PlayStation 4 Models

Sony first released the PlayStation 4 in November 2013 to critical acclaim. The original launch model with product code CUH-10XX featured impressive specs for the time including an AMD Jaguar CPU, AMD Radeon GPU, and GDDR5 RAM.

This original base PS4 was capable of 1080p gaming and served as many fans‘ entry into the world of modern console gaming in HD. It sold incredibly well right out the gate. But over time, Sony incrementally improved upon the PS4 formula.

First in June 2015, a minor upgrade launched with product code CUH-12XX. This model was nearly identical to the original PS4 except with a larger 1TB hard drive option.

It wasn’t until September 2016 that Sony released a major redesign – enter the PlayStation 4 Slim! Codenamed CUH-20XX, the PS4 Slim sported a thinner, lighter chassis, redesigned internal components, and better energy efficiency. This refreshed model provided the same performance as the original PS4 in a smaller package.

Hot on the heels of the PS4 Slim, Sony also unveiled their new higher-end console – the PlayStation 4 Pro. With model codes CUH-70XX, the PS4 Pro featured an upgraded GPU capable of 4K resolution and HDR visuals.

This was Sony‘s bid at a mid-generation upgrade to offer enhanced graphics and performance before the eventual launch of the PlayStation 5. The PS4 Pro became the go-to choice for players with 4K TVs who wanted the very best console gaming experience.

Now that we’ve covered a brief timeline of the PS4 models, let’s break down exactly how to decipher what the CUH codes mean and how they differentiate models under the hood.

Decoding the CUH Model Numbering Scheme

All PlayStation 4 model numbers begin with the letters CUH. This stands for Computer Unterhaltung Hardware, which is essentially German for Computer Entertainment Hardware. So any device that starts with CUH is a piece of gaming/entertainment hardware made by Sony.

After the CUH indicator, the first two digits in the model number represent the PS4‘s generation and series. For example:

• 10 and 11 = The original/launch PS4 hardware series
• 20 = The PS4 Slim revision
• 70 = The PS4 Pro series

So just from those first 3 letters and 2 numbers, you can quickly get a sense of which generation and model you‘re looking at.

The third and fourth digits in the model number stand for the specific region that the PS4 version was made for:

• 01 = USA and Canada
• 02 = UK, Europe, Middle East, South Africa, Japan
• 18 = China
• 33 = Korea

This region coding helps Sony track PS4 units and target manufacturing and distribution efficiently across different geographical markets.

Finally, the last letter in the model code refers to the PS4‘s hard drive capacity:

• A = 500GB
• B = 1TB

Putting it all together, a PS4 Pro model number might look like CUH-7215B. This indicates it‘s:

• CUH = A Sony gaming hardware device

• 72 = PS4 Pro series

• 15 = Intended for the US and Canada region

• B = With a 1TB hard drive

So while the model numbers look like random combinations of letters and numbers at first glance, each segment contains helpful coded information about that specific PS4 variant!

Comparing Specifications Across Models

Now that you know how to interpret the model codes, let‘s examine the technical specifications across different PS4 models to see how they differ under the hood.

Specification	Original PS4	PS4 Slim	PS4 Pro
Product Code	CUH-10XX/CUH-11XX	CUH-20XX	CUH-70XX
Release Date	Nov. 2013	Sept. 2016	Nov. 2016
Processor	1.6GHz AMD Jaguar 8-Core	1.6GHz AMD Jaguar 8-Core	2.1GHz AMD Jaguar 8-Core
Graphics	AMD Radeon (1.84 TFLOPS)	AMD Radeon (1.84 TFLOPS)	AMD Radeon (4.2 TFLOPS)
Memory	8GB GDDR5	8GB GDDR5	8GB GDDR5
Resolution	1080p	1080p	4K/HDR
Hard Drive	500GB/1TB	500GB/1TB	1TB
Dimensions	12" x 2" x 10.8"	11.3" x 1.5" x 10.4"	12.9" x 2.2" x 11.6"
Weight	6.1 lbs	4.5 lbs	7.2 lbs

You‘ll notice that the PS4 Slim shares nearly the same internal specs as the original PS4. The main difference is the smaller, lighter physical design. Sony focused on efficiency rather than raw power with the Slim model.

The PS4 Pro on the other hand received a nice performance bump under the hood. The upgraded Jaguar CPU is clocked ~30% higher than the original PS4. But the real game-changer is the souped up AMD Radeon graphics card rated for 4.2 TFLOPS of power – more than double the original PS4‘s GPU!

This gives the PS4 Pro the horsepower required to render games at up to 4K resolution or in HDR with enhanced lighting and visual effects. The extra juice makes a big difference, especially on 4K or HDR-enabled TVs and monitors.

Let‘s explore how this hardware translates into real-world gaming performance improvements…

PS4 Pro Performance and Gameplay Enhancements

Thanks to the graphics upgrade, the PS4 Pro can achieve higher resolutions, smoother framerates, improved textures, and shorter load times compared to the base PS4 models when playing supported games.

Here are some examples of how the PS4 Pro enhances popular games:

• Call of Duty: Black Ops 3 – Runs at native 4K resolution on PS4 Pro with enhanced shadow and lighting effects. Maintains a steadier 60fps framerate during hectic battles.

• Horizon Zero Dawn – Features 4K checkerboard rendering for incredibly sharp image quality. Additional visual enhancements include improved reflections, detail, and textures.

• God of War – Displays in 4K resolution while also adding finer graphical details, better antialiasing, and higher quality shadows.

• Uncharted 4 – Provides the option to favor either 1080p resolution at a smooth 60fps or 4K at 30fps. Overall visuals get a noticeable polish.

• Assassin‘s Creed Odyssey – Loads shave off ~33% on the PS4 Pro. Looks and runs best at 4K/30fps with enhanced draw distance and textures.

According to Digital Foundry benchmarks, the PS4 Pro‘s GPU can run ~73% faster than the base PS4 in supported titles when rendering at a full 4K resolution. This gives games the headroom to optimize for both higher graphical fidelity and performance.

Sony also released a PS4 Pro software update that allows you to "Boost Mode" on some older games that weren‘t specifically patched to take advantage of the upgraded hardware. Boost Mode uncaps the framerate allowing performance increases.

According to Sony‘s tests, here are some examples of non-patched titles running faster on PS4 Pro via Boost Mode:

• Fallout 4 – Improved framerate stability
• Project Cars – Up to 10% faster performance
• Battlefield 4 – Increased peak framerate by 7%
• Elder Scrolls Online – 8% improvement to frame pacing

So even without direct PS4 Pro optimization, many games still benefit! This ensures a solid experience whether you‘re playing cutting edge new releases or older titles.

Adoption Rates: How Popular is Each PS4 Model?

The PS4 Pro represented a major shift in console gaming by introducing iterative, mid-generation upgrades. But how well did this more advanced and expensive PS4 model sell? Let‘s look at some data on global sales and usage rates.

According to official figures published by Sony:

• 102.8 million PS4 consoles were sold between November 2013 and December 2019.

• As of December 2019, PS4 Pro made up ~16% of total PS4 sales.

• In March 2020, Sony stated 37.5% of active PS4 players were on PS4 Pro based on PlayStation Network data.

This means while the majority of gamers still use a base PS4, PS4 Pro adoption is significant. Almost 1 in 6 PS4s sold are Pros, and over a third of the current install base are Pro models.

The following chart summarizes PS4 model usage based on the latest official data from Sony:

So even though the PS4 Pro commands a price premium over the Slim and original models, it resonated with many hardcore gamers who wanted that extra performance edge. Its sales and usage figures demonstrate the appeal of more advanced consoles to a large segment of players.

Sony will surely take these adoption rates into account when designing future PlayStation hardware revisions and generations. The PS4 Pro paved the way as their first truly incremental upgrade approach.

Which Model Offers the Best PlayStation VR Experience?

The PlayStation VR headset is an extremely cool accessory that takes PS4 gaming to the next immersive level. But which PS4 model provides the optimal experience for virtual reality?

The PS4 Pro‘s extra horsepower makes it the clear winner here. The additional graphics capability enables higher rendering resolutions in PSVR games and helps sustain smoother framerates.

These improvements are crucial for providing comfortable, natural feeling VR gameplay. Small dips in framerate can cause nausea when the visuals don‘t line up perfectly with your head motion.

Digital Foundry compared performance across multiple PSVR games and found the PS4 Pro yields significant benefits including:

• 25% higher resolution in games like Battlezone
• More stable framerates with less drops
• Reduced aliasing thanks to better anti-aliasing
• Less pop-in as higher details are rendered further into the distance

The visual upgrade makes objects appear more crisp and defined in VR on PS4 Pro. This enhances immersion tremendously since you‘re right up close to the visuals surrounding your field of view.

Sony also developed a PSVR processing unit specifically for the Pro to help take advantage of the hardware improvements. This unit handles 3D audio processing and optimizes video output for the headset.

So while PlayStation VR will work on both PS4 models, I highly recommend the Pro if you plan to use PSVR. It really takes the VR experience to the next level.

My Personal Experience and Recommendations

I‘ve used all 3 major PS4 models extensively, and also upgraded from the original to the Pro. Here are some of my thoughts from first-hand experience:

• The PS4 Slim is great if you want a slimmer, quieter PS4 but don‘t care about 4K. It provides identical 1080p performance in a smaller footprint.

• For pure cost savings, a used or refurbished launch PS4 still performs admirably. I‘d only recommend this for buyers on a strict budget.

• The PS4 Pro‘s 4K and HDR visual enhancements are immediately noticeable, especially on a compatible TV. Everything looks sharper and more vibrant.

• Smoother framerates and faster loading times on PS4 Pro also improve gameplay. Control responsiveness ramps up the fun factor.

• I chose to upgrade to PS4 Pro after getting a 4K TV. The visual polish taking my favorite games to the next level made it worthwhile.

• If buying new, the Pro is absolutely worth the extra $100 in my opinion. The performance gains extend its lifespan.

So unless you‘re limited financially, I suggest going Pro. But you can‘t go wrong with any PS4 model. The base PS4 and Slim still deliver amazing gaming at 1080p resolution.

What Does the Future Hold for PlayStation?

While the PS4 generation has provided many memorable gaming moments, Sony is now looking ahead to the future PlayStation 5 console.

Sony officially announced the PS5 in 2019 and aims to launch it holiday 2020. The company is promising their "biggest generational transition yet" with cutting edge features like:

• Up to 8K graphics
• Ray tracing support
• Ultra-high speed SSD storage
• Enhanced immersive audio
• Backwards compatibility with PS4 games

And based on public interviews, lead PS5 system architect Mark Cerny says they are taking inspiration from the iterative approach pioneered with the Pro model while designing the new console.

For example, he highlights the benefits of using SSD storage rather than just increasing CPUs and GPUs. This demonstrates how the PS4 Pro informed their future thinking.

The PS5 will surely blow us away with some of the biggest performance leaps and technical innovations in PlayStation history. It‘s an exciting time to be a gamer!
