Sapphire Nitro RX 480 revealed

Looks much better in black than silver, although it is visually not the best design ever seen. But it is simple, thus not adding costs, which is definitely nice.

People's expectations of the RX 480:

OC'd RX480 may break the PCIe port due to the excessive electric current.

I wonder if they will cover the cost of replacement mainboards.

Less than 200 bucks for a card that gets this close to the 1070 (on paper)? That almost sounds too good to be true.

I like being right.

Sometimes, it does suck, though.

 

[GT_Alex74]

Althoug OCing it while there's already an acknowledge issue that AMD is going to fix pretty soon with a driver update was maybe not the most clever thing to do. And overclocking voids warranty usually so I wouldn't expect any kind of refund from them.

Guys, just wait for the third-party models. GTX 1080 Ti performance from a $200 card sound too good to be true? Well prepare to be amazed! Insane overclocking up to 1.21 jigahertz.

/AMD fanboyism

In all seriousness though, 3rd party boards might help reduce the sting of disappointment people with unrealistic expectations have been feeling with the RX 480... Don't expect miracles obviously, but we might at least get a reasonably overclockable model that won't burn out your PCIe slots.

Some good news after the power consumption problems - http://www.guru3d.com/news-story/ea...80-4gb-cards-actually-do-have-8gb-memory.html

Edit:

We promised an update today (July 5, 2016) following concerns around the Radeon™ RX 480 drawing excess current from the PCIe bus. Although we are confident that the levels of reported power draws by the Radeon RX 480 do not pose a risk of damage to motherboards or other PC components based on expected usage, we are serious about addressing this topic and allaying outstanding concerns. Towards that end, we assembled a worldwide team this past weekend to investigate and develop a driver update to improve the power draw. We’re pleased to report that this driver—Radeon Software 16.7.1—is now undergoing final testing and will be released to the public in the next 48 hours.

In this driver we’ve implemented a change to address power distribution on the Radeon RX 480 – this change will lower current drawn from the PCIe bus.
Separately, we’ve also included an option to reduce total power with minimal performance impact. Users will find this as the “compatibility” UI toggle in the Global Settings menu of Radeon Settings. This toggle is “off” by default.

Finally, we’ve implemented a collection of performance improvements for the Polaris architecture that yield performance uplifts in popular game titles of up to 3%. These optimizations are designed to improve the performance of the Radeon RX 480, and should substantially offset the performance impact for users who choose to activate the “compatibility” toggle.

AMD is committed to delivering high quality and high performance products, and we’ll continue to provide users with more control over their product’s performance and efficiency. We appreciate all the feedback so far, and we’ll continue to bring further performance and performance/W optimizations to the Radeon RX 480.

Revisiting the RX 480 vs GTX 1060:

 

[Techy]

lol this is quite a thread bump. But yeah, with the new ReLive drivers the 480 managed to beat the 1060, but it seems to be fairly limited to Vulkan or DX12 titles. With the usual DX11/10 games the 480 closed the gap with the new drivers, but not much. And of course the 1060 pulls ahead in Gameworks titles.

It's an interesting performance bump because when the 480 came out the 1060 beat it in a lot of newer titles. But with relive it closed the gap fairly significantly. The last gen Rx cards have improved somewhat as well, with an even bigger improvement in Vulkan or DX12.

 

[GT_Alex74]

The 480 still has another advantage : FreeSync screens prices over Gsync ones.

This is why I am reluctant in getting a G-sync monitor. You pay a hefty price premium for the G-sync module. Though I have seen a sizable price drop on a few G-sync monitors I've been monitoring..

Hmm would it be appropriate to post stuff about Vega?

Go ahead. 👍
Not really worth making a new thread, this one's pretty inactive as it is

 

[stonesfan129]

Did anyone see that new Threadripper CPU they're coming out with?

Yep 16 core 32 thread monster designed to take on intels 10 core i9 chip. The first Vega gpus will be aimed at deep learning applications and people speculate that gaming focus versions will come a short time after.

There was an AMA with Raja Koduri from AMD on Reddit which can be read here.
Recap (copied from this post):

• Main goal of Vega was to create an architecture that can handle large data sets and game at 4K at 60fps.
• The demo during Financial Analyst day was an air-cooled Frontier Edition, not an RX Vega card. There will be water cooled versions of Vega that will run slightly faster.
• Frontier uses 2 x 8GB stacks of HBM2.
  
• Both HBM1 and HBM2 provide plenty of bandwidth.
  
• Raja will look into OC'ing HBM2 and a 16GB RX card.
• RX Vega will be shown at Computex. It will not be available the same week but nothing else has been ruled out.
• Frontier runs comfortably using 1x6-pin and 1x8-pin but RTG put 2x8-pin on the production card for more headroom.
• Infinity fabric allows for the joining of multiple engines on a single die, and offers high bandwidth and low latency. There has been no mention of using Infinity fabric with multiple GPUs.
• Frontier was designed for an array of workload usages. RX Vega is for gaming and will be faster than Frontier.
• Vega will support Tensorflow, Cafe2, Cafe, Torch7 and MxNet via MIOpen.
• Pro versions support hardware virtualization. He did not state out right if this included Frontier/Vega or or not.
• The High Bandwidth Cache Controller (HBCC) helps increase minimum framerates and can improve performance even more if it's specifically coded for.
• Developing drivers for GPUs is really hard.
• Raja expects to grow ROCm to improve machine learning and compute. Another ROCm comment.
• Raja replies to a comment regarding particle physics simulation, saying this will be improved via the new cache and infinity fabric.
• New geometry pipeline in Vega improves throughput per clock cycle and will require no extra work on dev's part to utilize.
• Radeon Vega Frontier will be the fastest single GPU solution for compute.
• Radeon Instinct will provide dramatically better performance per dollar compared to the competition
• RX will have different drivers than Frontier that are optimized for gaming as well as additional goodies.
• Vega is the first GPU architecture to use Infinity Fabric and is in no way a re-hash of Polaris
• Radeon Chill will continue to be improved and will be updated soon.

Consumer Vega better be announced at Computex... Also more information regarding Freesync 2 would be nice.

 

[Techy]

Welp, Vega FE is slated for late June release. Consumer Vega, late July - Early August.
