GPUs enable rich, realistic visuals and explosive HD gaming performance
so you can dominate the competition.Whether you’re a gamer or movie buff
advised that you wanted to play the latest games or to enjoy a perfect
image quality in high definition, LDLC offers the appropriate PC Card
Chart. The purchase of a dedicated video card ASUS or MSI maximizes the
potential of your computer or simply exploiting the graphical interface
to your configuration.

The video card Sapphire HD 5770 Vapor-X runs at 860MHz GPU and 1200MHz
memory. Although the memory interface is 128-bit, is balanced by the
introduction of GDDR5 memory bandwidth ending 76.8GB / s. Unlike the HD
4870, which requires two 6-pin connector cord, the HD 5770 requires only
one. The maximum consumption will not exceed the minimum is 108W and
18W.  The ATI Radeon HD 577 0 is based on Juniper chip AMD GPU running
at 850MHz XE. Memory HD 5770 card runs at 1200MHz (4800MHz GDDR5 Staff)
and come with 1GB of GDDR5 memory. The card comes with 800 stream
processors, which is half the amount the Cypress chip. As bandwidth is
slightly higher than the HD 5750, which comes with 1150MHz memory and
73.6GB / s of bandwidth.

The results of operation under idle dropped temperatures hovering around
32 degree Celsius, while the active operation pushes that number up to
60 degree Celsius. Thanks to the cooling of vapor-X, the card is almost
inaudible at rest, and in full load, which is an additional incentive.
With regards to connectivity, the card has 2 Dual-Link DVI, HDMI and
DisplayPort, and as you probably know, depending on the configuration of
outputs for connecting to Ati Eyefinity Three LCD Monitors.

Overview :

Experience the extraordinary realism of DirectX game 11 with the new
processor series ATI Radeon HD 5700. Developed on the basis of the
fabulous HD 5800, these models have specific chip for a totally
immersive gameplay. Extend your visual support up to three screens with
the technology Eyefinity and accelerate multimedia applications
demanding the most resources with ATI Stream. As expected, AMD continues
its momentum by declining family of graphics cards DirectX 11 on the
mid-range. Just 3 weeks after the arrival of the Radeon HD 5800, so it
is the Radeon HD 5700 to arrive

To facilitate these Radeon HD 5700, AMD has developed a specific GPU,
codenamed Juniper. This is a kind of half Cypress, the GPU Radeon HD
5800. It is based on the same architecture and has the same features,
except the lack of support for double, but two times less processing
units and memory bus reduces from 256 to 128 bits. AMD announced it was
expected to quickly land the entire family of Radeon HD 5000. The ultra
high-end dual-GPU is scheduled for late this month or early November and
the entry level for early 2010. This is especially the case that the
arrival of Windows 7 approach. In renewing its range of graphics cards
just before, AMD is a huge blow, especially as it is the only one to
bear all the innovations introduced by this OS. It is of course to check
if these Radeon HD 5700 are indeed competitive in this segment shared
by many models and variations of all kinds. An exercise that is not a
foregone conclusion given the sale price off on this segment of the old

Integrates 10 processors each composed of 16 SIMD vector units 5D, a
total of "800 cores, such as marketing likes to refer to. It is
therefore an organization identical to that of the RV770 and RV790 the
Radeon HD 4800. Some minor improvements have been made to expedite the
processing of certain instructions, but in exchange, fixed interpolators
have disappeared. If it helps feed more efficiently texturing units, it
also consumes a part of computing power, which may have a slight
negative impact on performance. The main difference is however at the
memory bus as it is reduced by half compared to that of RV790. This is a
feature of the Radeon HD 5000: the report computing power / memory
bandwidth is increasing. Like Cypress, Juniper is therefore in this

Equipped with 1.04 billion transistors, Juniper occupies an area of 172
mm ² according to our measurements, against 334 mm for Cypress, 137 mm ²
for RV740, 281 mm ² for RV790 and 264 mm ² for Nvidia G92b. What to
offer a solution affordable DirectX 11. The specifications of these
cards vary in frequency, but also in terms of units 1 SIMD computation
since the 10 is deactivated, bringing the number of calculation units
vec5 160 to 144 or even the number of "cores "800 to 720.

Engraved in 40nm by TSMC, the RV840 chip has 1.04 billion transistors.
Its operating frequency varies depending on whether one considers the
Radeon HD 5750 or 5770. AMD Radeon HD pace from 5750 to 700 MHz while
the Radeon HD 5770 operates at 850 MHz. The memory frequency is also
different, but more slightly. The DDR5 powering the Radeon HD 5750 runs
at 1150 MHz to 1200 MHz against the Radeon HD 5770. The theoretical
memory bandwidth of the Radeon HD 5750 is thus around the 73 GB / s
against 76 GB / s for the model 5770. Among the features of the new
Radeon HD 5750/5770, we should note Eyefinity function. The chips of the
Radeon HD 5750 and 5770 can indeed handle three simultaneous display
outputs (their counterparts in the 5800 series support a total of six
screens). Finally, we find the Series 5700 support HDMI 1.3, which class
will include a carry uncompressed audio stream Dolby TrueHD and DTS-HS
Master Audio amplifier that handles the decoding.

Comparison to HD 4850 :

Compared to the Radeon HD 4890 Radeon HD 5770 has an output of
calculations identical, but a memory bandwidth of 40% back. It will be
interesting to observe the impact on performance. Radeon HD 5750 poster
of her later the same computing power than the Radeon HD 4850, however,
this time with a memory bandwidth higher than 15%, the latter was
equipped than GDDR3. 2 Radeon HD 5700 memory to use a very similar
specifications. The reference cards are equipped with GDDR5 memory Hynix
certified to 1250 MHz (2500 MHz for data). It is clocked respectively
at 1200 and 1150 MHz in the Radeon HD 5770 and 5750.

The Radeon HD 5770 is based on a PCB relatively short but the cooling
system exceeds somewhat. Under it, a metal plate is in charge of
dissipating heat from memory modules trapped under the hull, but also to
stiffen the card since the cooling block itself is set around the GPU.
One 6-pin power connector is required for feeding the Radeon HD 5770.
The Radeon HD 5750 reference provided by AMD has a design different from
the rest of the range. It has been simplified to reduce costs. Like its
big sister, a single 6-pin power connector required. All Radeon HD 5000
launched today occupy 2 slots and have a connector and a rear panel
identical. It features 2 DVI, HDMI and DisplayPort one. Three of them
can be used simultaneously, provided that the DisplayPort is among them.
Of course, the partners offer many customized versions of Radeon HD 5700
and especially the Radeon HD 5750 in the weeks and months ahead.

Digital Output:

The Radeon HD 5770 has a PCB (the map on which the components are
soldered) runs only 21 cm. However, the dissipater of origin is still
double height. If it is more cumbersome, it keeps a very acceptable
noise level in 2D. At rest, therefore, our meter observed 39.8 dB (A)
for a graphics chip maintained at 41 ° C. The card is barely warm and
the fan makes a breath noticeable but fairly unobtrusive. In operation,
the GPU does not heat up a lot and still maintained at 84 ° C for a
measured noise of 56.2 dB (A). The fan is very noisy when you play and
can disturb those around you (in a room for example).

Power Consumption :

The 5770 retains the same advanced energy management as its big brothers
in the 5800 series. At rest, our meter and showed 84 W while the figure
has climbed to 230 W during our test of intense 3D. These figures apply
to the whole machine and not only for the graphics card. Finally, only
one power connector 6-pin PCI-E is necessary. The data are obtained from
measurements taken at the exit of the outlet: it is therefore the total
consumption of power to the machine by a Cooler Master Real Power Pro
1250 watt. AMD has done a very good job in terms of consumption at rest.
In support, the use of 40 nanometers can not explode despite the
consumption of computing power.

Performance :

The card is intended primarily for owners of medium definition screens
(1680 x 1050). There, she can play with texture filters and activate all
the details on most games. Some titles guzzling (ArmA 2, Battleforge,
Crysis) will still see their graphics options reduced. Also, the card
offers performance well back from the old Radeon HD 4870 1 GB. Prime
example of results with World in Conflict: Soviet Assault. In 1680 x
1050 with the filters activated, the 5770 gets an average of 32 fps, 36
fps cons for 4870. In ArmA 2 in 1680 but still without the filters, the
average was 39 ips on the 5770 and 45 ips on the 4870. Finally, in Tom
Clancy’s HAWX in 1680 x 1050 + filters texture, the 5770 displays 52 fps
61 fps and the 4870.

Noise :

We measure the sound of one hand resting on the other hand the noise
after 30 minutes of charging, the test system is not outdoors but in a
housing Sonata 3. At rest, the Radeon HD 5700 are relatively quiet,
although the 5750 will do little to hear. Nothing serious though and it
must be very picky to notice. The results also his very proper care.

ATI Eyefinity :

The revolutionary technology ATI Eyefinity lets you expand your visual
support up to three screens to immerse you in the heart of the action.

Conclusion :

Based on the same architecture DirectX 11, these new cards aim this time
the segment mid-range. In a few weeks ago, AMD proposes a range DirectX
11 already consists of four references when NVIDIA has unfortunately
still nothing. The former founder of Sunnyvale thus benefits from free
field to display his arsenal. Note that contrary to the story as usual,
AMD chose not to use the name 5600 for its mid-range cards preferring to
go directly to the 5700 series.  But what are the new Radeon HD 5750 /
5770 and how they position themselves to face Radeon HD 4850 and 4770?
What are their characteristics? The response in the test that we spend
today to newcomers signed ATI.

We certainly regret the bus memory a bit cramped, despite the use of
GDDR5 memory type to fill the negative point that still remains a bright
spot: the use of a memory bus width of 128bit can only reduce
considerably the manufacturing costs at the expense of the use of video
memory a bit more expensive.  Both cards are based on the RV840 core,
better known by the name Juniper engraved in 40nm. Features are the same
as those of big sisters Radeon HD 5800: ATI Eyefinity management and
triple screen in native HD video decoding in hardware, Avivo HD and
whatnot like that.Again, AMD makes a masterstroke by offering consumer
graphics cards with a relatively well controlled, performance on paper
attractive, a rather successful card design and silent operation to the
task. You will understand, the green giant is well underway in the
campaign against nVidia GTX 260/275 offering at prices lower than ever.

Both the Radeon 5770 HD Radeon HD 5750 that are excellent products. In
addition to being ready for the new API from Microsoft, they perform
well, are relatively intensive and therefore do not suffer nuisance
derived from this point and then offer an extensive connection with the
support of three video outputs and bit streaming Dolby TrueHD and DTS-HD
Master Audio. More specifically, the Radeon HD 5770 struck the GeForce
GTX 260 + or Core 216 which costs more, consume more, is noisier and
does not support DirectX 11. In return, it increases, however, as all
Nvidia, the acceleration of PhysX owner. But even if the result is
rather convincing in Batman Arkham Asylum, this is not enough to offset
its weaknesses. The Radeon HD 5750 is also our preference over the bid
because Nvidia for the same price as the GeForce GTS 250 you will have
similar performance, but a more modern GPUs. And we’re talking here of
the version fast in the Nvidia GeForce GTS 250, as authorized in
versions less swift, is equipped with slower memory or a sub-GPU clocked
on the pretext of an opportunistic green edition.

If the Radeon HD 5700 still have to deal with fierce competition, it
actually comes from their own camp. The Radeon HD 4870 and 4890 have
indeed seen their prices drop significantly, mainly in Sapphire in the
case of the second. Suddenly you can find such a Radeon HD 4890 for the
price of a Radeon HD 5770 which in this case is not competitive in terms
of price performance ratio, even if it retains its other benefits.  It
is believed that these discounted prices on the old high end are related
to a desire to dump the stocks to make room for the new range. So this
could not last, but meanwhile there are bargains to be found, especially
as the availability of new entrants is limited, which draws some prices

Good points  :

  • Good performance
