Introduction and introduction to Ampere architecture
We got another version of the hottest hardware product around for the exam, in the form of a video card GeForce RTX 3080 GAMING X TRIO Made MSI. Are there justifiable reasons to get excited? Answers inside
In this review we present to you the performance and cooling capabilities of another sample video card GeForce RTX 3080, and is the GAMING X TRIO of the hardware maker MSI, Best known for its motherboards.
GeForce RTX 3080 Video Card NVIDIA It replaces the RTX 2080 Super and is preceded by the RTX 2080. This product fills a price box of about $ 700 and is considered premium for Gamers Who do not want a compromise between visual quality, resolution and high amount of frames per second. The very existence of RTX 3090 which will be launched soon does not make theRTX 3080 for a medium graphics card or with many compromises at all.
With the recent drop in prices and the increasing supply of 2560 × 1440 screens with 120Hz or higher frequencies, it is very likely that users will want to attach such a video card to a system that works with a new generation gaming screen. 1920 × 1080 resolution lags behind the more modest video cards, such as the GTX 1660 Super, RTX 2060 and their friends.
Among MSI video card versions, the GAMING X TRIO version is considered to be the most advanced available today, with a model without an X not included The fast Added from the factory to the graphics core frequency as in this model. MSI It is also known for slightly psychic models such as the Lightning, and there is a good chance that we will also see such at some point in the future, as their engineering takes some time.
Another series of MSI You will meet in stores is the Ventus series which comes in versions with 2 and 3 fans.
When the RTX 3080 and RTX 3090 models of this series come with slightly more modest heatsinks than what you will encounter in TRIO models but with the same fan technology, heatsinks and aluminum fans plus a very attractive and neutral theme. For all the technical specifications of each model we recommend Visit the MSI website.
Before we get down to business with MSI's RTX 3080 GAMING X TRIO card, a reminder of the technical features of the fresh Ampere architecture of NVIDIA.
Architecture Ampere Of NVIDIA
About two years ago we were exposed to the first architecture of NVIDIA Capable of performing fundraising (or Ray Tracing if you will) on a serious level. Beam tracking results in completely realistic lighting in XNUMXD graphics just as nature does, with accurate calculation of lighting by intensity, before the texture of the surface where the light strikes, and by returning light from surfaces to other areas.
The main components of the processing power within the graphics cores of NVIDIA SM units are generally responsible for geometric computing, RT cores (Ray Tracing) and Tensor cores for use in learning. In the Turing era that came to us with the RTX 20 series, the division was that each internal processing unit would have a certain amount of each resource. Core Like the TU102 which is the flagship of Turing It carried 72 SM units divided into 288 small processing groups (16 CUDA cores in each group), with each group also receiving 2 Tensor processors. All 4 groups received a single RT processor.
In the new Ampere generation, NVIDIA Decides to continue inflating its RTX card capabilities. The GA102 core as shown in the Geforce RTX 3090 video card contains in comparison 10,496 shading units, 328 Tensor units and 82 RT units per way. In the Ampere generation the counts of those SM processors, or CUDA units, are measured slightly differently as there are now two units in each individual communication tube, compared to one processing unit per tube in the previous generation. Therefore, 10,496 CUDA processors compared to 4,608 does not mean that we have doubled our shading processing power. It can be thought of as multi-threaded in main processors (HyperThreading technology of Intel for example).
This is what the graphics core of the Geforce RTX 3080 looks like under the hood. Roughly speaking, there is a division into five large processing arrays following communication with 10 microcontrollers זיכרון. Every such microcontroller speaks cattle זיכרון Main in the core and has a 32-bit channel which passes through the printed circuit board straight to the chip זיכרון. Not coincidentally, the Geforce RTX 3080 contains 10GB of זיכרון Graphic in 10 different chips. The core has a pool זיכרון 5MB second-level cache.
This is how one SM group looks at magnification, as it contains one new-generation RT core, four Tensor cores for learning and 128 CUDA processors. Using 68 such sets brings the graphics core to 8,704 CUDA processors and 68 RT processors along with 272 Tensor processors. All this in order to make real-time graphics more realistic and as fast as possible the image rate per second.
The Ampere core is manufactured in an 8-nanometer Samsung process. In fact, unlike many expectations to create in the popular TSMC plant, she chose NVIDIA At Samsung's factory and a relatively fresh production line that has recently become in demand (we know that the new Snapdragon for smartphones is also going to be produced there). The GA102 graphics core area on this video card is 628mm square, an area that is considered to be relatively large, but still lower than the 754mm square we saw in the TU102 core on the RTX 2080 Ti. However, the number of transistors has risen from 18.6 to 28 billion (!). The transition from TSMC's 12 nanometer process to Samsung's 8 nanometer allowsNVIDIA Produce graphics cores with tens of percent higher transistor density.
This video card uses a new micron memory called the GDDR6X. This memory is created to serve the large information traffic requirements of the new video cards, and currently exists only in the video cards of NVIDIA Models RTX 3080 and RTX 3090. The memory speed in this video card is 19Gbps and is about 320BIT bandwidth. This results in a total memory capacity of just over 760 GB per second. Depending on the composition of the memory controller, on each 32BIT there is chip זיכרון One of 1GB, so the total graphics memory volume is 10GB. This is an addition of 2GB compared to RTX 2080 Super The same graphics card replaces the price tag.

When MSI talks about fast core it means it with full intent. The RTX 3080 GAMING X TRIO operated at a frequency range of between 1975Mhz and 2040Mhz throughout all effort tests. These are quite aggressive frequencies for the Ampere's core NVIDIA.
As befits all TRIO models to date, the RTX 3080 GAMING X TRIO also features a body Cooling Huge with three fans (well… name map). In fact, the heat sink is significantly larger than the printed circuit board itself.
In terms of motherboards, the thickness of this video card is 3 slots, so it is important to note if you want to install additional devices nearby. In this look you can see the three electrical connectors of the video card and the serious lighting strip it has placed MSI. Later you will also see it in action.
The RTX 3080 GAMING X TRIO video card uses many of the components that can also be found in the RTX 3090 model such as the printed circuit board and heat sink, but also the power connectors. This video card requires three 8PIN PCI-Express connectors, which of course indicates its potential power consumption. Later in the review there are also some numbers. It can be seen that next to the electrical connectors there is a preparation for a double BIOS switch. Unfortunately, this video card does not include dual BIOS, as it is a feature reserved for MSI's RTX 3090 model. You can also see the five cooling pipes protruding on the back of the video card, they belong to the same body Cooling Massive bearing the X TRIO.
The back plate of the GAMING X TRIO is made of graphene according to MSI… only it turns out that it is not really the same exotic and expensive material, these are a combination of carbon and plastic. The heat goes better than traditional plastic, and here's the slight advantage.
The TORX fans of MSI We have been familiar for several years and here we get a new version. According to MSI, A union of any two blades with a convex tip aids in air concentration and thrust through the heat sink. At the base of each fan are two ball bearings.
In the remainder of the review we will look at the numbers and capabilities of this impressive heatsink in dealing with the formidable graphics core and 10 hungry GDDR6X chips.
The display interfaces on this video card with are completely standard. There is a single HDMI 2.1 port and three ports DisplayPort 1.4a. Since this video card does not vent hot air through the display interface area, I would be happy to see a port HDMI Another one. We know this is possible because there are models RTX 3080 others including this.
After we got to know theRTX 3080 GAMING X TRIO, it's time to move on to the meat and potatoes of every video card review, performance tests.
