What remains is still a very fast gaming board, albeit with a more budget-oriented cooler. Unfortunately, limited availability means there aren't many to go around. Pros

Features & SpecificationsA few weeks back, we published our Sapphire Radeon RX Vega 64 Nitro+ Review, introducing the first third-party Vega-based card to land in our labs. Compared to that board, Gigabyte's Radeon RX Vega 56 Gaming OC 8G is more understated, featuring easier-to-manage weight and dimensions. It's almost like this card was designed to be ordinary-looking, so as not to generate demand that Gigabyte wouldn't be able to satisfy. Nevertheless, this is a good example of a bread-and-butter solution that covers all of the bases and still offers a different approach than AMD's reference implementation. SpecificationsMarket & AvailabilityAccording to our sources, AMD's board partners have only received a few thousand Vega 10 GPUs, and most of those are destined for RX Vega 64 cards. Thus, a general shortage of packages is preventing anyone from mass-producing notable quantities of either model. It's simply not possible to start and stop a production line over and over again. It costs too much time and money. We were lucky to get our hands on a sample of Gigabyte's Radeon RX Vega 56 Gaming OC 8G, since we heard that fewer than 100 made their way into Germany. Buying a card of our own was the only way to get one into into the German lab. Here in the U.S., this is a mythical creature. Nobody has it for sale, and the only references online come from Gigabyte's site or product announcement news stories. Unboxing, Look & FeelWeighing just over 1kg, Gigabyte's card is an astonishing 600 grams lighter than Sapphire's Radeon RX Vega 64 Nitro+. This implementation is also considerably more compact, yielding a length of just 27.8cm, a height measurement of 13cm, and 4.7cm of width. Two counter-rotating fans, each with a diameter of 9.5cm, are positioned inside 10cm openings. According to Gigabyte, its unique fan blade design splits airflow and guides it through curves on the fan surface, improving flow compared to traditional fans. Naturally, we'll test the efficacy of those claims shortly. The backplate doesn't feature an Aorus logo, which was present on a pre-production model we briefly had our hands on. A copper insert placed on the back of the package is thermally isolated from this plate. Both components do play a role in cooling, though. Not pictured is a heat pipe that snakes around under the backplate, though we'll cover that in more depth, too. Plan for an extra 5mm of clearance (at least) behind the Radeon RX Vega 56 Gaming OC 8G. This may cause problems on some motherboards, particularly if the heat sink/back plate intrude on an occupied expansion slot or large CPU cooler. A peek in from the bottom shows that Gigabyte optimized the shape of its vertically-oriented fins. The slight tilt and wave shape are meant to create more efficient airflow, and thus improve cooling. Up top, it's apparent that Gigabyte paid close attention to cost. There are no RGB lighting effects or other gimmicks. Instead, you get simple injection-molded plastic and printed orange-colored highlights. The white Gigabyte logo is simply printed on. And similar to AMD's reference design, Gigabyte only requires a pair of eight-pin auxiliary power connectors. The closed back side doesn't reveal much. We catch a mere glimpse of two 8mm and three 6mm heat pipes, along with the fans' cable. On the board itself, we see solder pads for additional components (RGB output, perhaps?) that were obviously abandoned at some point during development. The I/O bracket is interesting because it features six connectors, rather than the reference design's five. Three HDMI 2.0 ports and three DisplayPort 1.4 outputs are available simultaneously, allowing you to connect six monitors in an Eyefinity array. In accordance with AMD's guidelines for clock rates, Gigabyte increased the Radeon RX Vega 56 Gaming OC 8G's base and Boost frequencies significantly. The company also upped its card's power limit by 55W.

To those complaining about the low supply (and resulting high prices) of AIB cards: It's because the reference cards are still selling very well (at least for their supply). If vendors can sell the $500 Vega 64 for $600 and sell out, why would they bother wasting time on any other model? That's because miners are the ones buying the cards as fast as they come in stock. It's us gamers and enthusiasts that are waiting for the high performance models. Bad thing is, we don't matter to the bottom line. All they see and want is our precious money, and they don't care what model they sell to us. Reply aelazadneBecause, the Vendor's making money doesn't equal AMD making money. AMD is losing market share in the GPU scene. With Vega unable to keep up with demand AMD is losing customers who would have bought Radeon's but instead go with Nvidia due to availability. The lack of Availability stemming from August and the fact that even now in early 2018 the Vegas are over priced and hard to find ruins customer confidence. In fact, this situation is so bad that the only people benefitting are the people gouging both Nvidia cards and Radeon cars because at this point there is NO COMPETITION. Also, just because you are gouging doesn't mean you are making money. AMD has to make money and they need to sell these things in a certain volume. In their contracts with Vendors, they will require their vendors to sell a certain amount of vegas in order to order more. Due to scarcity the only companies making money are Retailers. AMD is going to have to address this issue otherwise their investors will begin to come after them for bungling so bad that their market share dropped so bag. Literally, the intel screw up plus Ryzen being good has been a godsend for AMD, they do not need a declining GPU market share sparking a debate with investors over whether AMD should get out and play the Intel game.

For any of you who missed it, check out page 6 (Cooling & Noise) about 1/3 or 1/2 of the way down.

If vendors can sell the $500 Vega 64 for $600 and sell out, why would they bother wasting time on any other model? I think you're too cynical. It's an ASIC supply problem. The AIB partners would probably spend the time if they could get enough GPUs to sell custom boards in enough volume to offset the overhead of doing the extra design work. The only real way out of this is for AMD to design a more cost-effective chip with the graphics units removed. That will divert miners' interest away from their graphics products. Is Vega 64 good for gaming?10 Aug 2021 - Graphics card reviewedThe Radeon RX Vega 64 8GB will easily meet recommended system requirements of games released today. This is a strong benchmarker on modern games and can often return excellent frame rates at high and ultra 1080p. Is 750w enough for Vega 64?Would a vega 64 run with a 550 watt power supply :: Hardware and Operating Systems. No, you want a quality 750w PSU for the Vega 64. That CPU will go fine with the Vega. What is the Vega 64 equivalent to?It offers 64 CUs clocked at 1247 - 1546 MHz (Boost) and 8 GB HBM2 graphics memory. In games, the Vega 64 offers a similar performance as a Nvidia GeForce GTX 1080 on average. Does Vega 64 support 4K?We again see gains at 1440p, with the better AMD card coming close to both the GTX 1080 and RTX 2060, and at 4K the Vega 64 manages to beat out the GTX 1080 and come just 1fps behind the RTX 2070. |
