The new Titan is here. The RTX 3090 may not have a traditional name, but the $1,500 price tag and 24GB of GDDR6X memory indicate that this is a solid “professional-grade” GPU designed for scientists and content creators who consider the card to be an Nvidia professional The cheap alternative to Quadros-you will see in the final judgment, which makes us firmly a target customer. RTX 3090 is also known as a gaming monster, and can drive 8K displays even when 4K has not been widely adopted. This makes it a fascinating candidate for review because there is so much involved-the unique three-slot radiator, the built-in fully functional GA102 GPU and the efficient architecture of Ampere, all of which combine Nvidia’s promise to become the world The fastest graphics card. We will test this statement in the newly redesigned game benchmark test program, and give an impression of the hardware design and efficacy of the card.
As we pointed out in the RTX 3080 review, Ampere represents an important moment for the Green team. After experiencing the pain of introducing new features such as RTX and DLSS in the previous generation, which has moderately improved performance, the 30 series graphics cards have the opportunity to support these innovations at the original speed without the approval of gamers or developers.
Nvidia relies on chip shrinking to achieve this performance improvement, transitioning from TSMC’s 12nm process to Samsung’s 8nm process. If you compare RTX 3090 and RTX 2080 Ti, the new card has 50% more transistors, while its die is 20% smaller, which improves efficiency and performance.Combine this with architectural changes such as next-generation ray tracing and tensor core with With faster and more efficient GDDR6X memory, you can have a powerful graphics card. In the case of RTX 3080, this combination greatly improves horsepower, but using RTX 3090 only costs an extra $700, what can you get?

There is no doubt that part of this extra cash has been used for cooling solutions. The RTX 3080 FE’s novel “flow-through” cooler left a deep impression on us. There is a fan on each side of the card, but the 3090 FE takes it to another level. It has a true three-slot design (instead of the “three-seconds” we usually see), and the kitchen scale weighs 2.2 kg. The length of this graphics card is longer than the height of the Xbox Series X (we have checked it!), and you may have difficulty packing it in a standard box-so if you plan to buy one, double check the quota. The pennant-shaped PCB of the card allows the entire rear end of the card to be freely placed to leave a larger block of aluminum fins, plus the expansion volume of the card, you can obtain significant cooling performance. We don’t have equipment for rigorous thermal testing, but most of the time we see the card is spent between the 60s and 70 degrees Celsius, which means it has some of the best third-party cooling solutions.
Together with the RTX 3080 FE, the RTX 3090 Founders Edition is one of two graphics cards that support Nvidia’s new 12-pin power supply standard. At first glance, the 12-pin connector looks strange, but its clever design can plug a single port into an unprecedented power source-a smaller caliber than the dual or 38-pin inputs usually expected to be found on graphics cards. The 3090 PCB only extends to the middle of the card, so it is also located at the 12-pin input position. The 12-pin to dual 8-pin adapter in the box will be handy-if a bit too short to be seen-so if your 750W or higher power, you don’t have to worry about upgrading the power supply recommendation. Fortunately, if you prefer a neat appearance, the manufacturer of the modular power supply will sell or give away a dedicated full-length cable that terminates in a new 12-pin connector.
Like the RTX 3080, the RTX 3090 has a complete set of high-bandwidth ports, including one HDMI 2.1 and three DisplayPort 1.4a connections on the Founders Edition card we are testing. The HDMI 2.1 port is essential for high-resolution, high-refresh rate gaming on TVs and next-generation displays, because its 48Gbps bandwidth allows the display of 10-bit or 12-bit colors at 4K resolution and 120Hz refresh rate. It will also allow 8K connections at 60Hz-although there are few 8K displays on the market, Nvidia has invested a lot of effort in the marketing of its RTX 3090.
The support of 4K120 or 8K60 is consistent with Ampere’s new discovery of AV1 decoding, which is an emerging video standard with 50% higher efficiency than the popular h.264 codec. This will greatly reduce the amount of bandwidth required to stream high-resolution and/or high frame rate video and allow the delivery of video content up to 8K 60fps. Although the exact launch date of each service has not been announced, it has been confirmed that Chrome, Twitch and VLC all support AV1 decoding of RTX 3090.
The 3090 is also the only RTX model with an NVLink port that allows two 3090s to be hooked into SLI-although it is more suitable for data processing than gaming. Nvidia announced that it will no longer create any SLI driver configuration files after January 2021, so it is expected that gaming applications will be reduced from “limited” to “non-existent”.One thing you Used to What was found on the 3090 was the USB-C VirtualLink port. Sadly, this standard has never been mainstreamed in VR headsets.
Nvidia’s original Ampere revealed some impressive claims, one of which is particularly eye-catching: The company said that Ampere has ultra-high energy efficiency, is much better in power than Turing’s Turing architecture, and is achieved under the same performance. Almost twice the performance of Turing (relatively low)) power jacket. Nvidia did not accept better performance on similar power specifications, but referred to it as “one day use”, instead maximizing the available power of the new GPU-therefore, we saw the new 12-pin on the front Connector. Like the RTX 3080, Nvidia recommends that RTX 3090 owners use a 750W power supply and set the card’s rated power to 350W, which is 30W higher than the RTX 3080.
To see the power consumption and efficiency of RTX 3090 compared with early GPUs such as RTX 3080 and Titan RTX, RTX 2080 Ti and RX 5700 XT, we measured their power consumption and frame rate in “Death Stranding” and Gears 5. Both reached the maximum setting. The measurement is performed using Nvidia’s Power Capture Analysis Tool (PCAT), which is located between the graphics card and its power source (such as the PCIe slot and the 8-pin or 12-pin power input of the GPU), and measures the power to the card before passing. The test here is relatively simple-we measured the frame rate and power consumption in a specific scenario.
Watts per frame | RTX 3090 FE | RTX 3080 FE | RTX 2080 Ti FE | Titan RTX | RX 5700XT |
---|---|---|---|---|---|
Death stranded | 3.209 | 3.349 | 3.562 | 3.670 | 3.846 |
Percentage difference | 100% | 104.4% | 111.0% | 114.4% | 119.9% |
Watts per frame | RTX 3090 FE | RTX 3080 FE | RTX 2080 Ti FE | Titan RTX | RX 5700XT |
---|---|---|---|---|---|
Gear 5 | 4.055 | 4.156 | 4.266 | 4.291 | 5.403 |
Percentage difference | 100% | 102.5% | 105.2% | 105.8% | 133.2% |
The results here are fascinating. Although the TDP is higher, in the title we tested, a single frame generated by 3090 actually consumes less power than 3080: in “Death Stranding”, the power required per frame of RTX 3080 increased by 4%, and the power per frame Dropped to less than 3% Considering the amazing features of the RTX 3090, this sounds incredible-but the overall graphics processing power of the new card has increased by 12.5%, and the performance can exceed that number.
The next power band is RTX 2080 Ti and Titan RTX. In our static “Death Stranding” scenario, the power consumption per frame increases by 11% and 14%, respectively. The RX 5700 XT is another leap. This is AMD’s fastest graphics card at the time of its release (if you discount the short-lived Radeon 7) and consumes nearly 20% more power per frame-th is title performs well on AMD hardware . The Gears 5 test depicts a narrower area-in terms of efficiency, we are closer to the Turing card, but AMD’s “watts per frame” indicator is much higher.
In any case, the order remains the same. Among them, 3090 is the most efficient graphics card we have tested, followed by RTX 3080, then 2080 Ti and Titan RTX, and there is still some distance thereafter, while RX 5700 XT uses The rear is raised. Considering that the power range is more moderate, we expect the performance of the RTX 3070 to be higher than that of the 3080, but we never expected to see the 3090 achieve the same feat.
As we mentioned in the RTX 3080 review, we chose to update our test equipment for the first time in several years in order to prepare for the upcoming graphics cards from Nvidia and AMD. We replaced the Intel Core i7 8700K and ASUS Maximus 11 Extreme Z390 motherboards with the new Core i9 10900K, which was installed on the high-end ASUS Maximus 12 Extreme Z490 motherboard. The new equipment uses two 8GB G.Skill Trident Z Royal, the frequency is 3600MHz CL16, our memory frequency is slightly increased. These faster components should reduce the CPU bottleneck at lower resolutions.
Our storage requirements also exceeded the previous settings, and we chose the 2TB Samsung 970 Evo Plus NVMe drive provided by Box. The system is powered by a 1000W Corsair power supply, so we can easily meet the 3090’s 750W requirement-this may be the most power-hungry GPU we will see in the near future.
Please note that we are considering choosing the Ryzen 3950X test bed to take advantage of the PCIe 4.0 features of the new GPU, but our research shows that by sticking to the Intel test bed, we can get higher frame rates at lower resolutions-more importantly , Even at 4K, the performance should be equal RTX 3080 is limited to PCIe 3.0. In the future, we will continue to monitor the situation, but for now, all signs indicate that in some specific situations, the performance of the original CPU has a greater impact on performance than PCIe bandwidth.
