You may have stumbled across threads on the wild web created by AMD enthusiasts who have been undervolting their Vega cards and are bragging about it.  This will seem counter intuitive to overclockers who regularly increase the voltage their GPU will accept in order to increase the frequencies on those cards.  There is a method to this madness, and it is not simply that they are looking to save on power bills.  Overclockers Club investigates the methods used and the performance effect it has on the Vega 64 in several modern titles in their latest GPU review.

"Across all three games we saw a noticeable drop in power use when undervolting and not limiting the frame rate, or using a high limit. This reduction in power use is important as it improves the efficiency of the RX Vega 64 and it allows increased clock speeds with the reduction of thermal throttling."

Looking for an overclock? Try that ASUS ROG STRIX RX O8G GAMING family

[H]ard|OCP have posted their review of both of ASUS ROG STRIX RX O8G GAMING cards, one the Vega 56 the other the Vega 64.  The Vega 56 model comes with an overclock of 1297MHz core, 1573MHz boost and the Vega 64 is similar with a core of 1298MHz and boost of 1590MHz; both cards memory clocks are at stock speed.  [H]ard|OCP pushed them further with the Vega 64 set to 1700MHz and memory at 1050MHz in the driver while the Vega 56 managed 1720MHz and 850MHz memory, though it is worth noting neither card hit those speeds during use. 

In the end the Vega 56 model happily surpassed the GTX 1070 Ti, even without the manual overclock and while the Vega 64 did struggle to match the GTX 1080 in some games, it was the winner in DX12 and Vulkan games.  Check out [H]'s full review of the Vega 56 and Vega 64 to learn more about these two strong AMD cards..

The cult of Vega, FAR CRY 5 free with AMD systems

Subject: General Tech | February 27, 2018 - 12:43 PM |
Tagged: amd, Vega, farcry 5, ubisoft, RX 580, RX VEGA 64, RX Vega 56, gaming

If you purchase a custom built system with an RX 580 or either of the Vega cards, you will receive a coupon code which you can redeem for a copy of Far Cry 5 Standard edition.  Considering purchasing a full system is the only way to get a GPU for a marginally reasonable cost, it makes sense not to tie it to a GPU sale as has been tradition in the past.  UbiSoft have worked with AMD to ensure the game can take advantage of the various new features Vega offers such as FreeSync 2, Rapid Packed Math and Shader Intrinsics.  You can get more info on Vega here, or visit your favourite retailer for a look at qualifying systems.

"Gamers looking for smooth, more immersive gameplay as they join The Resistance and help bring down the cult, can get Far Cry 5 FREE when they buy select pre-built systems featuring Radeon RX Vega 64, Radeon RX Vega 56 or Radeon RX 580 graphics cards starting today February 27th 2018."

XFX Teases Custom RX Vega 56 and RX Vega 64 Double Edition Graphics Cards

Subject: Graphics Cards | December 1, 2017 - 02:48 PM |
Tagged: xfx, vega 10, Vega, RX VEGA 64, RX Vega 56, double edition, amd

Not content to let Asus have all the fun with X shaped products, graphics card manufacturer XFX is prepping two new Vega graphics cards that feature a cut-out backplate and cooler shroud that resembles a stretched-out X. XFX has, so far, only released a few pictures of the card but they do show off most of the card including the top edge, cooler, and backplate.

XFX has opted for a short PCB that extends slightly past the first cooling fan. The card is a dual slot design with a large heatsink and two large red fans and a bit less than half of the cooler extends past the PCB as a result. Cooling is not an issue thanks to liberal use of heat pipes (I think there are five main copper heat pipes), but the cooler hanging so far past the PCB has resulted in the two 8-pin PCI-E power connectors ending up in the middle of the cooler (the middle of the X shape) which is not ideal for cable management (still waiting for someone to put the PCI-E power connectors on the back edge closest to the motherboard!) but with a bit of modding maybe it would be possible to hid the wires under the shroud and route them around the card as one of the photos it looks like there is a bit of a gap between the heatsink and the shroud/backplate heh).

The design is sure to be divisive with some people loving it and other hating it, but XFX has put quite a bit of work into it. The red fans are surrounded by a stylized black shroud with a carbon fiber texture while the top edge holds the red XFX logo. The backplate specifically looks great with a black and grey design with red accent that features numerous cutouts for extra ventilation.

Display outputs are standard with three DisplayPort and one HDMI out.

TechPowerUp along with Videocardz are reporting that the card will come in both RX Vega 56 and RX Vega 64 variants. Unfortunately, while XFX has gone all out in the custom cooling and backplate, they are not pushing any of the clockspeeds past factory settings with the RX Vega 56 Double Edition clocking in at 1156 MHz base and 1471 MHz boost on the GPU and 1600 MHz on the 8GB of HBM2 memory. The XFX RX Vega 64 Double Edition is also stock clocked at 1247 MHz base, 1546 MHz boost, and 1890 MHz memory. It is not all bad news though, because with such a beefy cooler, enthusiasts should be able to overclock the chips themselves at least a bit (depending on how lucky they are in the silicon lottery) but it does mean that XFX isn’t guaranteeing anything. Also, overclocking might be more top-end overclock limited on the Vega 64 version versus other custom cards due to it only including two 8-pin power connectors (which does make me wonder what they have done as far as the VRMs versus reference if anything).

XFX has not yet revealed pricing or availability for their custom RX Vega cards.

What are your thoughts on the X design?

PowerColor Teases Custom RX Vega 64 Red Devil Graphics Card

Subject: Graphics Cards | November 17, 2017 - 10:09 PM |
Tagged: Vega, RX VEGA 64, red devil, powercolor, factory overclocked

Slated for a holiday release, images have appeared online of PowerColor’s upcoming Radeon RX Vega 64 Red Devil. The new custom graphics card is a triple slot design with a massive triple 85mm fan cooler. The shrouded Vega-based graphics card features red LED lighting that can be turned off with a hardware switch on the card itself. The shroud hides a 2.5-slot tall aluminum fin stack with contact to the GPU and VRM areas.

PowerColor is using an almost-reference design with a PCB that is slightly taller than AMD’s reference board and with two DisplayPort and two HDMI video outputs. It is not clear what the power input situation is with the Red Devil card with TechPowerUp reporting a two 8-pin configuration, but the images don’t reveal that and other sites aren’t corroborating that. One thing suggesting PowerColor may be sticking with two 8-pin PCI-E power connectors like the reference design is that they have not done anything crazy with the other power delivery components. While PowerColor is using different chokes, they are sticking with the reference 12-phase design with IR6894 and IR6211 DirectFETs and IR3598 phase doublers. The card does have a triple BIOS switch, so there is likely at least one factory overclocked option to push past the reference Vega 64 speeds of 4096 cores at 1247 MHz base and 1546 MHz boost.

According to Videocardz, the PowerColor RX Vega 64 Red Devil is slated for release later this month with availability at various retailers in early December. Further, PowerColor is also working on a custom RX Vega 56 card though it sounds like that one may not make it in time for the holidays. With the launch imminent, at least we will not have to wait too long to see the full specifications of this card.

The Radeon RX Vega 64 at 4K

Subject: Graphics Cards | October 20, 2017 - 04:30 PM |
Tagged: amd, RX VEGA 64, 4k

[H]ard|OCP updated their benchmarking suite with several new games and have published a review of AMD's Vega 64 focusing on 4K performance.  The race between the GTX 1080 and Vega 64 is quite close, with many benchmarks showing less than a 10% difference in performance.  Neither card came close to touching the GTX 1080 Ti, that card is still the only one that can truly handle 4K gaming with graphics options on high or ultra.  For 1440p performance, the GTX 1080 is better overall but the Vega is still a very strong contender. 
Pop over for a look at the detailed results.

"Does the AMD Radeon RX Vega 64 play games well at 4K resolution? What game settings work best at 4K, and how does it compare to GeForce GTX 1080 and GeForce GTX 1080 Ti? Ten games are tested, new and old, DX11, DX12, and Vulkan at playable game settings and pushed to the max in this all out 4K brawl."
