Question Radeon R7 450 (HP OEM 4GB GDDR5 version)? Anyone want to contribute knowledge/specs to the Hot Deal thread? Or take a peek at the price?

Trying to figure out this enigma of a card. It's available refurb for ~$60 from a Newegg Marketplace seller that I recognize.

Edit: If it's at least as good as a R7 260X 2GB, but with 4GB GDDR5 VRAM, then I'll not fret over wasting money on a few of these. (But the 260X had 896 GCN 1.1 shaders?)

According to wikipedia, these are first gen GCN Cap Verde chips with a 512:32:16 setup.

So essentially its a Radeon HD 7700, with 4GB of RAM. I'd avoid.

7770 had 1GHz core and 640SPs, this model is bellow that.
this sits between a 7770 and 7750 (same CU configuration as the 50 but higher clock than that)

4GB is nice, but this card is fairly limited anyway.

For $60 though? Will it do 1080P Med. gaming?

Why would you avoid? Lack of proper DX12 support? Other reasons? I thought that the 7770 was a decent GPU, only it usually came in 1GB and 2GB varieties.
The HD7770 was a decent GPU until about 5 years ago. 1st gen GCN does support DX12 fairly well, but for pure gaming, it's getting somewhat under-powered for more modern titles. Minimum specs are creeping up to a HD7870 or equivalent. Having 4GB of memory will not help there.

I suppose it could work well for eSport titles, but I don't think I'd aim higher.

For video decoding it lacks VP9 and HEVC support. It'll handle 1080p Netflix, but I'd think that's about it. But then, so will any modern IGP.

But the GT 1030 doesn't come in 4GB versions. (If it did, I think that would be hot seller for entry-level gaming, and Netflix 4K watching.)
The 1030 should be technically able to do 4K Netflix. Sadly NV arbitrarily chose a 3GB memory minimum requirement. Which means in practice we're limited to the 3GB 1050 or higher.

I think I've heard any 4th gen GCN card is able to do 4K Netflix, so maybe even the RX550 is able? Maybe someone could weigh on that?

Definitely not as good, Larry. At least 30% slower I reckon, but the extra memory can help in some situations, that's true. Hard to say without a sample on hand.

I believe a GeForce 1030 GDDR5 is faster than a 7770.
1030 is about the worst gaming card one can buy "new" in any shape or form.

2) Nvidia didn't bother to optimize Doom for the Kepler architecture, that's why the results are about ~33% lower than they should be.

Hard to say. Never had one myself, but reddit.

EDIT:

For budget gaming, I would consider something like a Geforce 1650 or its Super variant instead, even though, it only comes with 4 gigs of vram. This card is not meant to run Ultra settings in the first place, anyway. But it also makes A LOT of sense just to wait until fall to see what's new coming. I have high hopes of AMD's upcoming RDNA2 architecture, should be fully DX12 Ultimate compliant, just like Turing is now.

Alongside support for ray tracing and other RDNA 2 features, AMD has already confirmed that RDNA 2 is going to deliver a massive 50% improvement in power efficiency over RDNA, a feat which highlights how much AMD has improved their graphics technology in the run-up to the next console generation.

RDNA 2 will represent a massive leap for AMD in terms of efficiency, performance and hardware features, representing a transformative shift for Radeon's hardware stack. The demo video above showcases the ray tracing capabilities of AMD's early RDNA 2 silicon using Microsoft's DirectX Ray tracing (DXR 1.1) API.

Yes, I already have some GTX 1650 D5 refurb cards that I was able to pick up for $120-130 ea. Not horrible pricing, but why aren't they $110 new these days? That would fit the price/performance scale with $120 RX 570 4GB cards that are faster.

Price is not everything, Larry. Turing is fully DX12 Ultimate compliant, worth the premium, imo. Stick to 1650 for the time being, they are low power, come with efficient hardware decoder and excellent multi-monitor support. The only cheap/used card still worth buying for games is 1070. AMD is still lagging behind with its hardware support, especially with newer cards, unless you buy heavily discounted, not worth it, imo.
