Reports from HKEPC suggest that NVIDIA's upcoming GeForce GTX Titan Z flagship graphics card will feature a boost clock of up to 1058 MHz. In addition to that, we have also got a detailed look at the insides of the GeForce GTX Titan Z and the reason for its delay.
NVIDIA GeForce GTX Titan Z Can Boost Up To 1058 MHz
The official specifications chart from NVIDIA shows that the GeForce GTX Titan Z will feature the same heart and DNA of NVIDIA’s GeForce Titan and Titan Black Edition, the GeForce GTX Titan Z is an engineering marvel with two GK110-350-B1 chips under its hood that pack 7.1 billion transistors each. The GeForce GTX Titan Z will replace the GeForce GTX 690 boasting dual-GK110 cores compared to dual-GK104 cores on its predecessor. The GeForce GTX Titan Z will feature two GK110 cores with 5760 Cuda Cores, 448 TMUs and 96 ROPs.
The card features a 384-bit x 2 bus which will run across a massive 12 GB VRAM. This is an impressive feature giving developers and games an unprecedented amount of VRAM for use. The memory is clocked at 7 GHz effective clock speed. The core clock speeds are maintained at 705 MHz base and 876 MHz boost clock and the card features a maximum single precision performance of 8.1 TFlops and 2.3 TFlops of double precision which is impressive.
Now here's the interesting bit, we have all seen previous iterations of the GK110 core featuring some abnormal boost clocks which in some cases boost the clocks of the card much higher than the advertised frequencies. This translates into better gaming experiences and faster performance in visually intensive titles. The latest boost algorithm allows this so that the available TDP and Power headroom would be converted into higher clock speeds when required by applications. Due to this reason, HKEPC witnessed clocks as high as 1058 MHz on the GTX Titan Z as opposed to its official boost clock of 876 MHz.
The site also disassembled the card and let us on a detailed look at the main components of the card such as the VRM supply, SKHynix H5GQ2H24BFR-R2C memory chips (24 chips in total front/back), dual massive vapor blocks, PLX chip on the PCB that interconnects both GK110-350-B1 chips and a neat design that's toppled with a massive air cooler which takes up three slots. The card will feature dual black colored Vapor chambers placed on top of each GK110 core while a large cooler fan will push air from the internal assembly, cooling the components and letting the heat out of the front exhaust. The display outputs include Dual-DVI, HDMI and a Display Port. The card has a single SLI gold finger to enable two of these cards to function as multiple GPUs. The card is fed through dual 8-Pin connectors which represent a TDP of 375W. The card has a beefy 12 Phase PWM supply and with a 450W heatsink under its hood, the GeForce GTX Titan Z will actually be able to sustain overclocking on air around the 1 GHz mark.
NVIDIA GeForce GTX Titan Z Temperatures and Performance
Some surprising numbers from the report show a temperature of 57C in the first few minutes of running GPUz. The temperature will gradually increase with the passage of time and at 99% load. The boost clock however was static at 1058 MHz. The performance tested of the card at these clocks gave out a score of 13,735 3DMarks in 3DMark FireStrike.
The NVIDIA GeForce GTX Titan Z is planned for launch on 8th May 2014. The reason for the delay has to blamed on the NVIDIA drivers which were not ready to be shipped during the last month. The new official drivers which are named GeForce 337.69 is a press driver and a WHQL variant would be available to consumers during the launch day.
