Time for some GDDR5
Written by John M   

 

Now that the GeForce GTX 280 is out, you may be wondering what the alternative from AMD will be like. Well, for starters, it will have GDDR5, something the first GTX 280s don't. Quimonda, or was that Infineon? is more than ready to mass provide GDDR5 (Graphics Double Data Rate) memory modules. Other manufacturers like Hynix Semiconductor, or Samsung, will also jump onto that wagon, but it looks like having skipped GDDR4 entirely, in favour of GDDR5, gives Quimonda the edge, here.

The chips waiting to be produced are configured at 512 Mb and reach a speed of 4.5 GHz. This could translate, with a 512 bits memory bus, into a bandwidth of roughly 300 GB/s. Top of the line graphics cards form AMD/ATI are sure to benefit from the improvement, while nVidia should also join the fun (it's anyone's guess just how soon they will). It would actually be time for them to leave GDDR3, like ATI did (when they adopted GDDR4 in 2006).

After almost five years of GDDR3 rule (let's face it, GDDR4 was never a big deal), it's time for a new push in graphics memory performance that doesn't rely on the expensive bus trick. GDDR5 won't be cheap either, but in the long term prices will go down.

More performance expectations from the RV770
Written by John M   

 

Man, are we going to be sick with numbers before they become official. No such thing as a review yet, but somebody who the folks at Vr-Zone refer to as CJ has more to add (let's pray he didn't get them from another forum).

The RV770PRO with GDDR3 at 1 GHz, should be 25% faster than the GeForce 8800 GT/9800 GT. The RV770XT with GDDR5 at 1.96 GHz, 25% and 30% faster than the GeForce 9800 GTX and the 4850 (RV770PRO). Remember that the 4870 will not only have faster memory, but a 100 MHz core advantage.

Okey dokey, that's out of the way, now let's talk about your hard earned (or not) money. If DigiTimes is correct then the ATI Radeon HD 4850 will be "only" $229, the 4870 about $349 and the 4870 X2 between $529 and $549 (ouch). Release dates are still (keep your fingers crossed) June, end of July and... the rest of the year, respectively.

The Radeon 4800 gets delayed
Written by John M   

According to AMD's new agenda, the 48xx series won't be out until the week from the 15th to the 22th of June (gossip has it that the exact date will be the 18th). That's about a month's delay if we recall the initial release date.

The immediate consequence of this delay it will be that nVidia will get the upper hand in the upcoming battle for the next generation of graphics cards. That is, if they don't screw it too when it comes to releasing their own GT200.

Starting from the sub $200 level, where you can expect to find a 4850 with 512 MB of memory, the prices for the 4870 and the 4870 X2, which will hopefully make it's entrance in July, will be from $249 to $299 for the first, and from painfully to unearthly expensive for the X2. Don't forget that their competition will be the "I want your penny" GeForce 9900. Oh, and another thing, they say these cards will have physics processing capabilities.

May Best Deals for Graphic Cards
Written by John M   

 

The may edition of Tom's Hardware version of "what the heck do I spend my money on, this month", graphics card roundup is live. We've got four price ranges: up to $110, from $130 to $160, from $175 to $260 and from $300 to $350. Jurassic AGP cards have their own reserve.

In the budget area they hint these models: the Radeon HD 2600 XT, the GeForce 8600 GT and the GeForce 8600 GTS (now we start to see why they didn't choose the more rounded sub-$100 range, looks like they wanted to include the last one). Mainstream arena is the place for the likes of the GeForce 9600 GT and the Radeon 3870 (even if it costs a little bit less, I think the GeForce 8800 GS can't be compared). On the high end, you can pick from a single GeForce 8800 GT to a GeForce 8800 GS SLI configuration. And finally, if you're Mr loads-a-money, then by all means, don't look at anything else than any of the mainstream or high end cards in SLI.

Theres still a place for AGP cards
Written by John M   

 

The lack of new products for the ageing interface was rather upsetting, but yesterday AMD announced the availability of two graphics cards for this platform: the Radeon HD 3650 with 512 MB and the 3850, both of them AGP 8X.

The Radeon 3850 shouldn't be considered as a novelty and the 3650 adds some credit because it represents a chance for those who want to update their PCs but not their motherboards. If you have a somewhat old computer, it's not likely you'll be willing to spend 139€ on the more expensive of the two, but now you can opt for the other one, which only costs 89€ and should be more than enough for you to feel the difference.

Finding nVidia AGP cards is difficult, to say the least, but AMD continues to offer alternatives to buying something old and paying for it as if it were new (it's perfectly possible that someone might ask of you some 30€ for a GeForce FX5500 with 256MB, for example).

AMD and nVidia ready for a new battle in Summer
Written by John M   

GeForce 8000 series and 55-nm process are news of the past (as recent as this past may seem) so both AMD and nVidia are looking forward to launch their next-generation high-end graphics processors. They have completed tape-out of the chips and they (the chips) should already be being mass produced by foundry supplier TSMC (Taiwan Semiconductor Manufacturing Co.).

With this early roll out, I guess we can say it's back to the six to nine months cycles we were used to see not so long ago. Thats good news for us buyers.

AMD is prepearing RV770, while nVidia works on the GT200, which consists of roughly one billion transistors and 200 unified shader processors. But no DX 10.1 just yet, sorry guys.

Radeon HD 3870 X2 reviews galore
Written by John M   

 

Before nVidia gets it's act together with the Geforce 9800 GX2, AMD will be in the lead with the new Radeon HD 3870 X2. And it will accomplish that with a graphics card that, even though it's basically a single board CrossFire solution, isn't longer than a GeForce 8800 GTX (or an Ultra) and costs roughly twice what a single 3870 does.

If you don't play Enemy Territory: Quake Wars, you will be happy to hear that AMD dominates all the other single card configurations. The only thing AMD has to worry about here, is the fact that a SLI set-up with two 8800 GTs looks to be better.

When it comes to power consumption, it eats 56W more than an 8800 GTX (playing Bioshock). This data lacks precision, but it's clear that two cards need more power than one even if they are placed on the same PCB.

Radeon HD 3690 better than expected
Written by John M   

 

For those that don't remember, the Radeon HD 3690 (55nm RV670 Pro) is here to substitute the recently introduced HD 3850. According to it's nomenclature, it should find a place between the 3650 and the 3850.

Selling for little more than $100, this card was supposed to perform closer to the 3650 than to the 3850. Specifications are nearly identical to those of the higher rated chip, but with a memory bus that's been reduced to the half (from 256 to 128 bits), there was little hope that it would be much better than the 3650. Hope, they say, is the last thing you should lose.

In this article from the guys at PCPOP we see the new GPU pitted against the 3850 and a couple of nVidia cards in the same price range. The verdict is completely different if you look at 3DMark or pay attention to real games. Synthetic tests say the 3690 is clearly inferior to the 3850, but the only game that sees a similar behavior is Call Of Duty 4. Crysis, Lost Planet, Company Of Heroes, World In Conflict, BioShock, Age Of Empires 3, HL2: Episode Two, UT3, NFS: ProStreet and Quake Wars favour the 3850 too (all of them), and they do it by a healthy margin in some cases, but not as much as to have a great impact on playability.

Considering the price difference, it could be a good buy.

 
Radeon HD 3450 - budget gaming or HTPC?
Written by John M   

 

With the RV620, AMD/ATI has finished it's 55nm product line-up. Following the footsteps of the RV670 (aka 3800 series), which came out first, and shortly after the RV635 (3600 series), the 3400's target buyers that are less interested in 3D gaming, and more in price and the options to build an HTPC.

This graphics card has some characteristics that, because of it's limitations when it comes to games, seem rather useless:  DirectX 10.1/ Shader Model 4.1 support, PCI Express 2.0 or CrossFire technology. Others like DisplayPort and PowerPlay (for more efficient energy managment), will, on the other hand, end up being quite interesting.

This chip is very similar to the RV610, and shares many goals with the HD 2400, so let's see how it compares to the "Pro" version. As far as CPU utilization is concerned (during video playback), the new Radeon isn't much of an improvement. Where it does help, is in games, achieving 26.73% more frames per second. You can reduce the difference to 6.31% by increasing core and memory speed on the 2400 Pro, but you could also overclock the 3450 if you wanted, right?.

nVidia GeForce 9600GT
Written by John M   

 

The GeForce 9600 GT should be the first card from the 9000 series to surface (right away) and it's time to get some 3DMark numbers on it. Using a quite powerful Core 2 QX9650 on an Asus Maximus Formula X38, we obtain something very akin to what the 8800GS can muster. These results are good news for you, because it was known that the 8800GS wouldn't last. It's this new graphics card that has to fill this market sector.

The 9600 works at 650/1625/1800MHz (core/shader/memory) and it's G94-300 based (not G92). If 3DMark doesn't cut it for you, here you will find a lot more: from technical specifications comparisons (between 9600GT, 8800GS, 8600GTS and Radeon HD 3850), to fully detailed chip surface measurements. Of course, the game list for the benchmarks is long, and not only includes 3DMark 2006 Ver. 110, but: Call Of Juarez, Lost Planet: Extreme Condition, BIOSHOCK, Company Of Heroes Ver. 1.70, Crysis, Need For Speed: ProStreet, F.E.A.R, Unreal Tournamant 3 Demo and Colin McRace: DIRT.

In this case, "only" a QX6800 on a Gigabyte GA-P35-DQ6 with two gigabytes of memory and Windows Vista (for DirectX 10 support) form the system setup.

Radeon HD 3670 256MB
Written by John M   

 

The mainstream graphics cards market is really heating up, with both nVidia's 9600GT and AMD/ATI's RV635 promising more frames at a lower price point.

It looks like the 8600GT will have a more than worthy successor but, can we say the same for the HD2600? Compared to the equally clocked version (the 2600XT), the answer may be "no". Even with a reduction in the fabrication process from 65 to 55nm, the new GPU gives very little in the performance area to justify the raise in power consumption.

Leaving aside the results for the HD 3670 256MB in Half Life 2 Episode 2 @ 1600x1200 without AA, which should be more driver related than anything else, the frame rates are very close to label the new product as a success. Power consumption could also be explained by the chip being an engineering sample, we leave the conclusions up to you before further results are published.
