Ever wondered what the difference is between all those GPUs with fancy names and designs? You’ve likely come across the term “reference GPU”. But what exactly is a reference GPU? In this guide, we’ll break down the concept of reference GPUs, explaining their role in the graphics card market and how they compare to the other options you might encounter. By the end, you’ll be a reference GPU pro, ready to make informed decisions about your next graphics card purchase!
What Is a Reference GPU?
A reference GPU, also known as a “reference design graphics card”, is a model created by the company that develops the graphics processing unit (GPU) chip, like NVIDIA or AMD. These companies design a basic graphics card around their new GPU to showcase its capabilities.
- The reference GPU allows the chipmaker to demonstrate the raw power and performance of their new GPU.
- The reference design also serves as an inspiration for AMD and NVIDIA’s hardware partners who will create their own custom graphics cards based on the new GPU.
A reference GPU like the NVIDIA RTX 3090 or AMD Radeon RX 6800 XT allows you to see what the graphics chip is capable of, excites hardware partners to build even better custom graphics cards, and gives early adopters a chance to experience the power of the latest technology. But for most, waiting for custom cards with better features is worth it.
The Role of Reference GPUs in the Industry
Reference GPUs, like NVIDIA’s Quadro line of graphics cards, play an important role for professionals in industries like engineering, architecture, and design. As a beginner, you might wonder why companies develop reference GPUs when consumer graphics cards seem to work just fine for most people.
Superior Performance
Reference GPUs are built specifically for high-performance, workstation tasks, not gaming. They have faster clock speeds, higher memory bandwidth, and optimized drivers to handle complex 3D modeling, video editing, and CAD software. The additional power under the hood allows professionals to work with huge datasets and render complex graphics in real time.
Certified Drivers
The drivers for reference GPUs are tailored to work with professional design and engineering applications. They go through rigorous testing and certification to ensure maximum compatibility and stability. Companies that make expensive workstation software actually work with GPU vendors to optimize performance. Generic graphics drivers simply can’t provide the same level of support.
Reliability and Support
Workstations housing reference GPUs are mission-critical tools for many companies. Downtime can cost money, so reference GPUs are built to very high standards for reliability and longevity. They also come with dedicated customer support teams to quickly resolve any issues. For time-sensitive projects, quick turnaround on support requests is essential.
Expanded Features
Reference GPUs provide features important for professional use but rarely found in consumer cards, such as 10-bit color support, stereoscopic 3D support, and multiple DisplayPort outputs to drive several 4K monitors at once. They may also have special outputs for virtual reality headsets, 3D monitors, or other emerging technologies used in certain industries.
How Reference GPUs Differ From Retail GPUs
Specifications
Reference GPUs typically have very basic specifications since they’re meant primarily for testing new architectures and technologies. They usually lack advanced cooling systems and overclocking capabilities found in retail cards. Reference boards also tend to have lower clock speeds and less onboard memory. These stripped-down specs allow developers to isolate and evaluate the performance of the new GPU architecture or components.
Availability
Reference graphics cards are not commercially available for purchase. They are distributed directly to developers, OEMs, and journalists for review and testing purposes. Some tech enthusiasts are able to get their hands on reference GPUs through private selling forums and marketplaces, but supplies are very limited since they are not mass produced. By the time a new GPU architecture is launched for retail sale, reference boards have usually been phased out.
Drivers
The drivers for reference graphics cards are beta versions that are still in development. They have not gone through the same rigorous testing and optimization process as retail GPU drivers. While the beta drivers are relatively stable, they can introduce performance issues and software bugs. If you do get a hold of a reference GPU, the best option is to install the latest retail drivers to ensure maximum compatibility and reliability.
- In summary, reference GPUs provide an early glimpse at new graphics technology but lack the polish and performance of retail graphics cards. For most PC users, “retail GPUs” are superior for actual usage due to their optimized designs, mature software and broad availability. Unless you’re a developer or hardware enthusiast, retail graphics cards are the better choice for everyday computing needs.
Nvidia’s Common Reference GPU Models
Nvidia is known for releasing new graphics cards models over the years that push the envelope in performance and features. However, they first release a “reference design” version of the card that they send out to reviewers and partners. These reference GPUs establish a baseline for the architecture and capabilities. Board partners then use the reference model as a starting point to customize, improve cooling, and overclock for their retail cards.
The GTX 1080 Reference Card
Back in 2016, Nvidia released their Pascal-based GTX 1080 as a reference card with 8GB of GDDR5X memory and 2560 CUDA cores. It delivered amazing 4K gaming performance for the time and was a glimpse into the potential of the new Pascal architecture. The GTX 1080 reference design featured a blower-style cooler that exhausted hot air out the back of the case. Board partners released their own custom GTX 1080s shortly after with improved coolers for lower noise and temperatures.
RTX 2080 Ti Founders Edition
In 2018, Nvidia launched their Turing architecture and the GeForce RTX 20-series. The flagship RTX 2080 Ti came first as a “Founders Edition” reference card with 11GB of GDDR6 memory and 4352 CUDA cores. This reference model had a more premium dual-fan cooler and fetched a higher price. It established the performance and feature set of ray tracing and DLSS that board partners tailored for their custom RTX 2080 Ti models.
Other Reference Cards
Nvidia has continued the trend with reference versions of the RTX 2070, RTX 2060, GTX 1660 Ti, and RTX 30-series establishing a baseline for partners to build upon. While reference card designs provide a first look at new GPU architectures, board partner custom cards typically offer better value with lower prices, improved coolers for less noise and heat, and factory overclocks for extra performance. Nvidia’s reference GPUs remain an important first step in showcasing new graphics technologies.
Why Reference GPUs Are Important for Benchmarking and Testing
Reference GPUs are specialized graphics cards made specifically for benchmarking and testing other consumer graphics cards. They are designed by GPU manufacturers like NVIDIA and AMD to provide a standardized baseline for comparison.
1. Consistent and Powerful
Reference GPUs pack some serious power under the hood with high-end components to handle intensive graphics processing. More importantly, they have tightly controlled specifications so they perform consistently. This means if you run a graphics benchmark on two identical reference GPUs, you’ll get very similar results.
2. Establishing a Baseline
The performance numbers from reference GPU tests create a baseline that allows you to compare how other graphics cards stack up. If a new consumer card gets slightly lower frame rates in the same benchmarks, you know it’s a bit slower than the reference model. But if it produces significantly higher frame rates, you know you’re getting a boosted performance over the reference standard.
3. Simulating a “Worst-Case Scenario”
Reference GPUs are meant to simulate a “worst-case scenario” for a graphics card model. Since the components are standardized, it shows you the minimum level of performance you can expect from a card based on those specs. Custom consumer cards from third-party manufacturers will often add their own tweaks and overclocks to improve performance, but they should never perform below the reference level.
4. Pushing the Limits
The powerful components in reference GPUs are also useful for pushing graphics technologies to their limits. GPU makers use them internally for development and testing of new architectures, interfaces, and other technologies before rolling them out to consumers. They provide a controlled environment to ensure things are working as intended before releasing to the mainstream.
- Reference GPUs play an important role behind the scenes, even though they’re not really meant for ordinary gaming setups. They establish critical baselines and help shape the development of new technologies that ultimately make their way into the graphics cards you use every day.
