As the majority of the cards are using stock cooling methods, it makes sense that the temperatures are, for the most part, similar save for the MSI GTX 275 Twin Frozr OC.
Comparative analysis of NVIDIA GeForce GTX 275 and ATI Radeon X1650 PRO videocards for all known characteristics in the following categories: Essentials, Technical info, Video outputs and ports, Compatibility, dimensions and requirements, API support, Memory, Technologies. In general, we saw that the HD 4890s were running nearly 25% hotter than the GTX 275 at idle, but the Radeons were actually somewhat cooler than the GTX 275s under load. NVIDIA GeForce GTX 275 vs ATI Radeon X1650 PRO. Since we're on the subject of power consumption, which is related to heat, we also made note of the minimum and maximum temperatures recorded by the GPU sensor using HWMonitor.
Under a full load, however, the total draw was typically slightly less than the GTX 275. Installing any of the Radeons upped the idle draw to 194W, nearly 30-40W more than the GeForce GTX 275. Write a comment below.When equipped with a GeForce GTX 275, our system pulled down from 155W to 164W at idle, and then almost double that when under load conditions. 2560 x 1600 60Hz Max - digital interface (all Dual-Link DVIs)Īll cards require additional power, so each is bundled with a molex to 6-pin adapter, even though all modern PSUs have with such cables.2048 x 1536 x 32bit 85Hz Max - analog interface.The GTX 275 card has a TV-Out for an S-Video cable. We could even overclock the core to 750/2000 MHz without ruining stability. We'll analyze temperatures below, and operating stability of this card is really high.
The company promises lower operating temperatures and stability. Power consumption is lower now (as PSU components consume power as well as like core and memory chips). In fact, this PCB is heavily modified (layout, protective screens and their quality, power supply). Its PCB only looks like reference (even though it's manufactured by Gigabyte, not purchased from NVIDIA as a ready product). It should be added that the card allows to adjust its operating frequencies and voltages with a special utility.
On the other hand, it comes with a massive cooling system (to be described below). Although equipped with a 256-bit memory bus, this PCB is designed as short as possible. The GTS 250 is apparently a unique card designed by Gigabyte. These memory chips are designed for the maximum frequency of 1250 (2500) MHz.Ĭomparison with the reference design, front viewĬomparison with the reference design, back view The graphics card has 896 MB of GDDR3 SDRAM allocated in 14 Hynix memory chips on the front side of the PCB. These memory chips are designed for the maximum frequency of 1250 (2500) MHz. The graphics card has 1024 MB of GDDR3 SDRAM allocated in 8 Hynix memory chips on the front side of the PCB. Output connectors: 2xDVI (Dual-Link/HDMI), TV-out.Dimensions: 270x100x33 mm (the last figure is the maximum thickness).Memory frequencies (physical (effective)): 1130 (2260) MHz (typical).GPU frequencies (ROPs/Shaders): 633/1400 MHz (typical).Output connectors: 1xDVI (Dual-Link/HDMI), 1xHDMI 1xVGA.Dimensions: 210x100x32 mm (the last figure is the maximum thickness).Gigabyte GeForce GTS 250 Overclocked 1024MB We have two products based on NVIDIA GPUs from different price and performance ranges: GeForce GTS 250 (aka 9800 GTX+, based on the good old G92) and GeForce GTX 275 (an intermediate between GTX 260 and 285, closer to the latter in terms of speed). This article is devoted to new graphics cards from Gigabyte.
