Any reviews on the HD 4860?

[Illyan]

I just saw this card on newegg: http://www.newegg.com/Product/Produc...82E16814102866

Does anyone know of any reviews or benchmarks for it? Is it closer to the 4850 or 70? It's $130 right now, so it doesn't seem to make much sense price-wise.

You could always try Google...

Anyway, a quick search netted this review:

Seems about 5% faster than a 4850. Doesn't make much sense to me, considering how crowded ATi's upper midrange lineup already is (4850, 4870, 4870X2, 5850, etc).

interesting specs, i am wondering if this is based off of the 4890 with a disabled sp unit?
4860-700mhz 640spu
4890 850 800
4870 750 800
4850 625 800

It looks like it has the same amount of stream processors as the 4830, but with a faster clock speed (575Mhz vs 700Mhz). Looks to me to be closer to a 4850 than anything else.

Stock of the 4800s is shrinking fast, and thus this part has a place if only because 4850s and 4870s are becoming harder and harder to find at bargain prices, and the 4890 is solidly more expensive.

Its a shame the GPU is cut down, in lower resolutions it could be slower than a 4850 (700MHz, vs 625MHz might help a tiny bit) but the GDDR5 is much welcomed. I'm curious about overclocking though. If it has volts like the 4870, it might be able to hit 750-850MHz core which would definitely help make up for the lack of SPs. The memory is also something of interest. Unless they're using slower/older GDDR5, its possible this has faster chips that can overclock to 1000+MHz (from the 750MHz stock)

Very interesting card. Looking at just the specs, it looks closer to the 4850 than the 4870. I wouldn't even say it's necessarily faster than the 4850.

4850:

Memory Bandwidth-63.552GB/sec
Flops-1000GFLOPS
Pixel fillrate-10000Mpixels/sec
Texture fillrate-25000Mtexels/sec

4860:

Memory Bandwidth-96GB/sec
Flops-896GFLOPS
Pixel fillrate-11200Mpixels/sec
Texture fillrate-22400Mtexels/sec

4870:

Memory Bandwidth-115.2GB/sec
Flops-1200GFLOPS
Pixel fillrate-12000Mpixels/sec
Texture fillrate-30000Mtexels/sec

If one could overclock the 4860 GPU to 785Mhz, the 4860 would be slightly better than the stock 4850 in every way.

I agree, it seems like it's a sink for rejected 4890 chips. It would make sense. It looks like an excellent card, but it'll trash the 5750 and 5770 market segments - with the exception of DX11, this is an excellent little card. It's too bad AMD didn't go with such a memory configuration for at least its 5770 part.

That's what xbitlabs said here.

2 power connectors?

In this card famine time any decent performer is welcome.

Lol, video card famine, never thought that would happen

All the better to overclock with .

lol, very poetic

there's always hope for a 5790 or a 5830

This part looks over priced to me.

640 sp @ 700 Mhz? This is slower than HD4770.

Granted memory bandwidth is improved but still it is 55nm and a slower GPU.

It's great for a crossfire set-up (reminds me of the G80 configurations - slower GPU with monster bandwidth). However, I believe the complexity of the 256-bit memory bus and the PCB in general drives the price up.

Also, is this a Sapphire exclusive (like the 4850X2) or are they just first to market?

Now you've got me interested. I could count on not being short of video memory bandwidth when running 2900 in Crossfire. The fill-rate on my 9800GX2 gives much higher framerates, but there's not much room for overclocking the memory.

As ever, it will depend on price vs other cards in this performance segment of the market.

I'm also looking for some crossfire action with this card.

 

[MrK6]

Well, another interesting thing to look out for will be what kind of RAM chips they stuck on this card. If they're cheaper 4.0Gbps chips (or actually 3.0Gbps, as listed, didn't know they made those), that would kind of kill the benefit if they don't overclock well. A 5770 can get close to 90GB/s bandwidth with an average ~1400MHz speed, and has a much faster GPU.

Any new news or reviews on this 129$ card?
Really would like to try some crossfire action with these and hopefully get 310$ 5850+ performance on the cheap 250$. Newegg has 10$ off when you buy 2 of these.
