Based on the Ampere architecture, NVIDIA has played a flower, first GeForce RTX 30X0 series graphics card normal decline update, and then GeForce RTX 30X0 Ti series graphics card second round of attack, these two waves of operations have piled up new graphics cards into the mid-to-high-end graphics card market, and GeForce RTX 3050 such entry-level is delayed. Recently, NVIDIA fell in love with the suffix of 12GB video memory, and quietly launched the GeForce RTX 2060 12GB and RTX 3080 12GB to the market.
That's right, it's really the RTX 3080 12GB. The RTX 3080 queue actually has two products, namely the RTX 3080 10GB released in September 2020 and the RTX 3080 Ti released in July 2021, and there is a certain difference in positioning and performance gap between the two graphics cards (about 8.5%). At the beginning of January 22, the main launch of RTX 3080 12GB seems to be a rich product line, but in the author's eyes, this graphics card is more to meet special needs, such as creators, or miner.

Two more SM units than the RTX 3080
If you simply think that RTX 3080 12GB is only the gap in the display capacity, then you are wrong, Lao Huang's knife method can be called "out of the blue", no core is the old Huang a knife can not be cut, if there is then go back to the furnace to rebuild it.
You'll see the RTX 3080 12GB with a new core number: "GA102-220", which is a core with a higher specification than the RTX 3080 10GB (number: GA102-200).
The two RTX 3080s also use the core of THE GA102, but the RTX 3080 12GB has more SM numbers, 2 more than the RTX 3080 10GB, the number of stream processors has reached 8960, and the RT Core/Tensors Cores/TMUs/ROPs have also been increased to 70/280/280/96, in theory, the RTX 3080 12GB core specifications are higher, and the performance must be more powerful.
It's not just 12GB of video memory
The video memory increase to 12GB is really not as casual as imagining a change of particles, RTX 3080 10GB has a 320bit memory width, just 10 memory particles composed of 10GB of video memory. If you want to increase the capacity of the memory, or directly change a single GDDR6X memory particle with a larger capacity (at present, the Micron official website has not announced 16Gb density particles), that can only be the GA102 core of the memory position wide completion.
So you'll see that the memory width on the RTX 3080 12GB graphics card is 384bit, so just two single D8BWWW GDDR6X memory particles with a capacity of 1GB are completed to form a 12GB memory.
It is worth noting that the RTX 3080 12GB graphics card specifications are higher, the performance is also stronger, but the requirements for power supply are also higher, its TDP has reached 350W, so AIC graphics card manufacturers will use the form of dual 8Pin auxiliary power supply, and some overclocked versions are more likely to use the higher specification auxiliary power supply of three 8Pin.
Shadow Chi GeForce RTX 3080 Obsidian MAX OC [FG], exterior
As a new work in the Obsidian series, Yingchi GeForce RTX 3080 Xingyao MAX OC[FG] (hereinafter referred to as "Yingchi RTX 3080 Xingyao MAX OC") continues the unified folding design of the Xingyao series, and the surface shell also has a transparent crystal shell, which can facilitate everyone to create the graphics card for secondary creation.
If you don't know how to create secondary content, you can refer to the "Shadow Chi RTX 3070 Ti Star Obsidian OC Forever Doom Edition Review" before this site.
Take apart the crystal shell to see the pure white wind shroud inside, which can be graffiti, or stickers... The above figure is what we did when we were evaluating, the method is relatively simple, but the appearance value is also obviously improved.
The back is a custom metal backplane that acts as a reinforcement of the graphics card PCB
The skeleton backplane and skeleton PCB design is really more popular on the 30 series graphics card, and this design is really good in practical applications, with the chassis air duct to accelerate the rapid drainage of the graphics card hot air.
Just now we said that the RTX 3080 12GB graphics card has soared in demand for power supply, so as an overclocking version of the Yingchi RTX 3080 Xingyao MAX OC is equipped with dual 8Pin auxiliary power supply. Theoretically, it can provide a maximum of 576W of power supply, but based on the PCIe specification limited to 300W power supply, with the PCIe slot 75W power supply, to meet the RTX 3080 12GB 350W TDP is not a problem at all.
The three 9cm fans and the top BOOMSTAR logo all use RGB design, which can use the Yingchi light control software to create personalized faith lights. Of course, it is connected to the motherboard through the 12V VRGB same frequency cable, and the motherboard lighting control software can also be used for the same frequency control of the light effect.
Indy GeForce RTX 3080 Obsidian MAX OC [FG], disassembly
Since the RTX 3080 12GB originally uses the GA102 core, the Yingchi RTX 3080 Xingyao MAX OC directly uses the PCB and heat dissipation of the GA102 solution.
The Inchi RTX 3080 Star Obscurity MAX OC graphics card PCB adopts a shoulder-over design, and the whole PCB obviously has a higher and longer design. The power supply of the entire graphics card is quite powerful, and the 16+4 power phase design is stronger than the GTX 3080 Ti FE public version.
The core number that can be seen in the close-up shot is GA102-220-A1, and the core is 21 years and 48 cycles and products. On the side around the core are 12 Micron GDDR6X particles (numbered D8BWW) forming a 12GB 384Bit video memory specification.
The layout of the non-public PCB of the 30 series flagship graphics card is much more complex than that of the 20 series, mainly because the core and GDDR6X video memory have much higher power supply requirements.
The front and back rows of the GPU are power supply templates, and the simple decomposition is that the GPU core is powered by 16 phases, of which 10 phases are NVVDD, 6 phases are MSVDD, and the video memory requires 4 phases of independent power supply.
Each phase of the memory is powered independently by a DrMos chip in the MPS 86990
The PWM control chip of the graphics card, multiple MPS control chips coordinate the control
What is more interesting is that Yingchi equipped the graphics card with a dual 8Pin power supply with an independent metal cover, which can ensure that the interface is not susceptible to thermal melting, and the interface will be more stable.
The front power supply is equipped with a fully blackened metal heat dissipation module
Intuit RTX 3080 Xingyao MAX OC heat sink adopts a three-stage five-heat pipe heat dissipation module, and the memory and power supply modules are equipped with thermal pads to assist in heat dissipation
The entire radiator is nickel-plated, and the anti-oxidation effect is good, which can make the radiator have a longer service life and easier dust removal.
The reflow soldering treatment is adopted between the heat pipe and the heat dissipation fin, and the heat dissipation effect should be good.
Introduction to the test platform
The old version of GPU-Z 2.43.0 did not correctly identify this new RTX 3080 12GB graphics card, we need to update to the latest GPU-Z 2.44.0 to recognize the RTX 3080 12GB and RTX 3050 graphics cards. However, even if it cannot be fully recognized, the approximate specifications are the same as those given by NVIDIA.
Looking at the frequency of the Yingchi RTX 3080 Xingyao MAX OC graphics card, the basic frequency is still 1260MHz, but the Boost frequency has been increased to 1755MHz, the BIOS version is 94.02.85.00.BC, and the power consumption limit is still 350W, but the maximum can reach 380W.
Theoretical performance comparison
Here we use a more comprehensive 3DMARK theoretical performance project for the comparison test of three graphics cards, in general, the shadow RTX 3080 12GB graphics card fully meets the specifications of the performance of the period positioning, weaker than the RTX 3080 Ti specifications, but stronger than the RTX 3080 10GB, just in the middle of the position, can only say that the old yellow demon knife has always been like this.
Since the Yingchi RTX 3080 Xingyao MAX OC is an OC version of the graphics card, the performance in the Fire Strike project is quite good, and its GPU reaches 2025MHz at 40s, which is much higher than the 1755MHz of the Boost frequency, which is a stronger power supply and better heat dissipation.
Creator capability performance comparison
There are a few problems with the creator test, RTX 3080 Ti FE several test performance is relatively low, the author believes that the new version of the driver and made, RTX 3080 Ti FE uses 497.29, and both RTX 3080 use 511.09. But after the test, NVIDIA launched the latest version of 511.23, which was a bit disgusting.
Then we directly take the creator performance of the two RTX 3080 graphics cards to compare well, RTX 3080 12GB thanks to the core specifications and the advantages of video memory, the performance is still about 4% ahead.
Some people will say that excluding the gap in core performance specifications, 10GB and 12GB video memory is actually not a big gap, the author can take the UL test on the video memory occupation to tell you, 12GB is still quite necessary, the current mainstream picture and video test project is based on the mainstream 1080p and 4K video creation, but with the continuous development of technology, the camera pixels are getting higher and higher, and the production of 6k8k video is also quite easy. 4K resolution already occupies 9.4GB, so what will the 8K resolution be? It is estimated that 12GB is the beginning at that time.
Game performance comparison
Game performance, Yingchi RTX 3080 Star MAX OC graphics card is simply if there is a divine help, the performance is not worse than RTX 3080 TI FE, that is, 4K resolution, the gap is only opened some, but 2% of the performance gap, the difference is so much money, or it is recommended that you buy RTX 3080 12GB.
Compared with the RTX 3080 10GB graphics card, the Yingchi RTX 3080 Xingyao MAX OC graphics card is 8% ahead of the performance difference, which is completely to open up a large gap, so that the current RTX 3080 12GB graphics card is still relatively high. Let's take a look at the highest image quality of the graphics card in the 4k resolution game, and the video memory occupation after the light chase is turned on, which is about 9964MB. If it is a graphics card with 10GB video memory, it is really possible to burst the video memory.
Power consumption versus temperature
In fact, from the official information given by NVIDIA, we already know that the TDP power consumption of the RTX 3080 12GB graphics card has reached 350W, and the Furmark grill also reaches this TDP upper limit. It's just that because the Yingchi RTX 3080 Xingyao MAX OC graphics card is a non-public graphics card, the GPU temperature and memory temperature performance is much better than the FE public version, especially the temperature is really high under the high frequency stability of GDDR6X.
Let's take a look at the performance of the Furmark roaster with the DETAILED PERFORMANCE OF THE MAX OC graphics card, the grill is 14 minutes, the GPU core temperature has stabilized, the GPU frequency is 1455MHz, the fan speed is 52%, and the noise performance is quite ideal. At the same time, we found that the PCIe slot is borrowed for 47.2W, while the 8Pin#1 is powered by 143.5W, and the 8Pin#2 is powered by 158.2W.
summary:
RTX 3080 12GB graphics card is really good, of course, the price is really high, but for the current graphics card market is an inflated price, RTX 3080 12GB has a clear stream feeling, performance is stronger than RTX 3080 10GB, game performance is close to RTX 3080 Ti. If you can't buy a flagship graphics card, the RTX 3080 12GB is really a good choice, whether it's a gamer or a content creator.
And the Yingchi RTX 3080 Xingyao USED in this article MAX OC graphics card is the RTX 3080 12GB graphics card in the jiaojiao, high frequency, strong power consumption, solid materials, heat dissipation performance is also very strong, then really buy RTX 3080 12GB can consider the Yingchi RTX 3080 Xingyao MAX OC graphics card.
